WHAT PEOPLE SAY
I have been buying these kits for a while now and there the best kits I've ever bought!!!! I suggest these to anyone that is ready to buy a kit. there very powerful and have everything you need to build a quality bike. the customer service is top notch and if there is a problem he will fix it right away.
Hello California Motorbikes,
I'm Anthony from Northern Michigan and I purchased a Wildcat motor kit from you guys May of 2016 and mounted it on a Huffy Cranbrook. I road it all summer. Your Wildcat kit is seriously one of the best purchases I've made in my life! It runs very strong after I tuned the carb and added a higher compression slant head. (mine had arrived with a flat head unfortunately) I am SO HAPPY that I bought your balanced motor because it doesn't vibrate! My brother had bought a cheap Ebay motor and it vibrated very badly. Ebay motors are crap! Please keep up the sourcing of good balanced motors! you are the ONLY seller I know of that sells balance motors, and I'll be ordering from you guys again when I do a 29" bike build this summer. Feel free to use any or all of this as a review, I want other motorized bike enthusiasts to know that they can buy from California Motorbikes with confidence!
BTW, the comparison pictures on the "why our engines" page on your website is what persuaded me to buy your kit...so many sellers say that their kit is the best without showing what is better. Rock on!
Got my bike and is awesome ride about 52 miles on it every day and run so smooth thanks again all my buddys are interested in getting on now:)
I have about 130 miles on it so far and am very happy with it!
The only thing that I was unhappy about was that I never got an email receipt, and no tracking number, when I emailed them about it I got no reply. But I recived the kit in a week or less. So all was good!
I think if I were to get another kit , I would use them again.
I like how this kit has everything you need , and more. It has the gear puller with it, and the wide front engine mount, if you need it. So I am happy with them. Keep looking up! Ken.
Happy customer in Sacramento CA, Average 150 to 200 miles per week hauling my trailer every where with a 7 year old in tow, No issues at, been running strong since August 2015.i don't know how to post a review. Please feel free to use this for a review, will be returning customer when necessary.
I have been riding gas bikes for over a year now , i have had 4 engines , the 1st one was from a piston bikes com , it ran for 1500 miles and sputters then the bike was stolen. i got a new one a few months later from here on California motor bikes , it was a bit rough at first but once i got it tuned it ran good for 600 miles until my workmanship (bent wheel) caused damage to the cylinder , i then bought another one and put another 2500 miles into it before i wore it out. recently i purchased one for a few dollars less then the wildcat and i still have not gotten it to run CHEAP CRAP!!!! gasbikes.net , thats all they sell is crap . i will be buying a new on and I WILL GET IT HERE BECAUSE THESE ENGINES RUN!!!! i speak from experience !!!
Very happy with my purchase, runs really well, only issue was the tensioner mount would loosen which was an easy fix with a piece of inner tube between the mount and frame . , Its a great motor and i would defiantly recommend it for anyone that needs something dependable for transportation or leisure riding. Mine is mounted on a 26" mountain bike and goes faster than i need so im happy with my purchase andbought another just to have around for a spare. :)
I purchased the 80 cc Wildcat Engine Kit and It was Very Easy to Install. The provided instructions were easy to follow and it took only a couple hours to complete. I filled the tank ..primed and set the choke and it started up on the second crank. It has plenty of power. California Motor Bikes is the only company I Would recommend buying from for 2 reasons. 1. Fast Shipping... 2. Quality Parts and Advice. Great Job !
I am writing this review and I would like to explain that I have had very good experience. I have bought seven engines, 2 four stroke engines and 5 2 strokes. Anything I need I can call or text he's there. California motorbikes helps fix any problems that have, thx again lovemy bikes.
Greetings California motorbikes I purchased a wildcat engine kit for my huffy Cranbrook it fit perfect with the adapter plate and u bolt that came with kit its a heavy bike but with balanced wildcat engine I blow by the competition no problem I have friends with lighter more expensive bikes with ebay walmart engines im faster and way less vibration I can let my bike run on kick stand doesn't fall over my buddy tried that broke cluch handle when it fell over well his was plastic mine is aluminum plus I havent striped any hardware on wildcat no junk Philip head screws and my chain hasnt came off not once I also pull a 2 seat childs trailor cant feel it back there it truely halls the mail ive started a bussiness building these bikes and California motorbikes will be my source for kits anything I needed help with they didnt hesitate to help me through my learning curve per this was first bike ive built. And lastly I compared wildcat with outher engines the wildcat isn't false they dont lie on advertising everything is true from the crank to the hardware to the chain to the sprocket all is better quality than ebay and walmart kits I did the footwork so thanks again california motorbikes
You have always been a great help , your engine kits have been the GREATEST kits on the market I'd recommend your kits to everyone ....... Keep up the good work thanks alot!
Engine runs like a boss. Customer service... outstanding. I had a rare defect in my first engine and although no warranty is offered I was issued a replacement. Try getting a replacement off of ebay from China... not gonna happen. 5 stars.
The engines are great quality from here. I push my engine to the extreme every day. I'm creeping up to the 4,000 mile mark on the motor with few mods done. I got mine to reach 53 mph gps indicated with some mods.
Ok so I ordered this kit from California motor bikes and I cannot argue that these people gave me some of the best customer service I have ever had. Since I live in Australia it is a lot harder to get motorised bike motors and parts shipped to me, but these guys did an amazing job at getting the kit to me. If you are from another country I highly recommend buying a kit from California Motorbikes. I can't thank you guys enough for helping me out and delivering my kit to me. They said that they don't get many international orders so to see that they handled one that well blows my mind. Keep up the great work guys and I am looking forward to ordering from you again!
Great motor that screams , the only 2 problems I had was throttle cable was too long and carburetor. Bolt wouldn't hold carb on intake, the fix for carb was a hex cap bolt from Loews and the cable fix was to cut it and solder a new ball on the end. Superior motor, keep up the good work.
When I got my kit in the mail, I noticed the cylinder was cracked. I messaged you guys, and you sent me a replacement without any hassle. I'm loving this engine. It's balanced so much better than cheaper ones you find online. And much sturdier mounting hardware.
By far the best, smoothest and longest lasting kit engines in the industry. Without the hype and overpriced so called race engines. The no- mark rod and crank are as close to balanced as it gets for the price. Good communication, fast shipping and no B.S.
Fantastic kit overall!! Shipped without plug ,fuel filter and fuel line. Didn't get to opening the kit for a week or so, email California motor bikes about the oversight. Received a reply within a few hours apologizing for the oversight and 3 days later I received the overlooked parts. Motor is going to be a wonderful build. I will order your Wildcat PK 80 for any and all of my builds whether for myself or customer builds. I updated a kid in my neighborhood bike. CNC machined head and expansion chamber. 30 tooth sprocket and re jetted the speed carb and this thing is a rocket off the line even though I have a small rear drive sprocket. Along with the spring tensioner I am truly impressed with the quality of the up grades to this young man's motorized bike. Safe to say that whether it's performance part upgrades or Motor kits I have found my supplier. Well done and Thank you.. Drg Mechanical and Fabrication!!!
Bought this pk80 wild cat several months ago around January of this year just install own my bike today, took it for a spend around the neighborhood a few times, and must say this wildcat exceeded my expectations, so far i'm very satisfied with this engine performance, so far it's everything California motor advertise, i will definitely be purchasing another one in the future, this is a true review from a real customer, keep up the good work.
