The instruction book from Mike Simpson was much more informitive than Dax's and if you want to see the whole review thread on a different forum, I can PM you the linkI got my Dax 70cc kit today for the new bike...WOOOO HOOOO!!! First impression was mixed. Some good things in the kit and some not so good things.
My first Grubee 48cc round head kit came from Motorbikemike (Simpsonmotorbikes.com) and I was pleased with it.
Mike's kit came without a fuel line or a fuel filter...Dax's kit came with them.
Mike's kit came with the beefy motor mounts...Dax's kit has the wimpy stamped steel ones.
Mike's kit came with extra, long mounting studs and mounting blocks...Dax's kit had 1 extra mounting block and no extra, long studs.
Mike's kit comes with the nice plastic throttle with the built in kill switch...Dax's come with an aluminum throttle (which has a throttle body sized for a 7 year old's hand) and the seperate cheesy kill switch.
Dax's kit comes with a better engineered air cleaner...Mike's has an older style that just happened to break on me 2 days ago (going to have to do the beer can treatment)
Dax's kit comes with the heavy duty chain...Mike's does not (could be because Mike's was a 48cc)
Dax's kit came with a matching grip for the non-throttle side...Mike's had no matching grip.
Other than those thing, the kits had pretty much identical items, i.e., chainguide, chainguard, tank, petcock, tool kit, instruction manual, etc.
I am very excited to try out the new roller bearing kit from Dax and I hope it treats me to miles of "bug it teeth" grins! More to come as the project takes form.
I purchased one of Chris Hill's kits and am very happy with it. Have not had any problems. After each run for any length of time I check head bolts and ect with a precision torque wrench and none have loosen up. He appears to have done excelent work on the engine. I run the 44 sprocket and am going to try the 36. Here in Corpus the land is very flat. I have put together another bike with the Honda GX50 frame mounted and the Grubee 111 centrifucal clutch gearbox. The gearbox sounds like a thrashing machine at low speeds and lightens up on the noise factor as you increase speed. I have taken it apart several times to lube all bushings,bearings and gears but to no avail.Hey there Biker...welcome to motorbicycling.
There are a lot of things to keep in mind when you make your purchase...least of all should be the bottom dollar on eBay, unless you don't mind dealing with headaches and issues.
Your best bet is to ask questions (lots), read as much information as you can with regards to what is available out there. If you can find any reviews, read them carefully and compare what you find out to other engines and dealers. The other good thing is to ask other riders what engines they are riding, and if they have had any issues with the engine or the dealer. Consider the warranty that is being offered, and what it consists of...does it seem fair?
Also, ask yourself about what you are purchasing. Does it make sense that you could really purchase an engine of decent quality for that price?...chances are if the price seems almost to good to be true, it likely is.
Cruiser is more than right when he says that not all these engines are the same...even though they may look very similar...it's what happens on the inside of that engine that decides if it is quality or not.
I hope the above information (or lack of) didn't sound like any type of sales pitch. The link for my website is in my signature for that purpose, lol. I am just offering advice on how to find a good engine.
Naturally, I would say that my engines are the best there is, but that wouldn't be a good thing to say unless my customers say it too...and they do.
If you have any questions, please feel free to get in touch with me.
