Dax 1.5" friction kit - Tanaka 40cc - DH bike

[lowracer]

Here is my latest MB.
I had such a positive experience riding the front drive Rocky Mountain RM7 DH bike around w/ various engines, that I decided to sell my other 2 hardtail MB's & build up another DH bike. I found a lightly used 2007 Banshee Scream on feeBay & won it for $780. Had a pocket bike stage 2 cag on for starters but installed a Tanaka 40cc (sweet engine).
Here a few pics before & after.
The last pic is how its setup now.

That bike is awesome. The orange fuel tank seems unusual. Did it come with that? Is it colored by the fuel you are using?
How does the bike do at holding top speed? I have the 33 cc and I don't think mine could push a 1.5" roller well. You have the bigger engine and power pipe though, so that is probably enough to keep it from struggling.

This new Tanaka PF-4000 came with the orange paint & orange fuel tank. It better matches my other MB since its black/orange. That one has the 32cc Tanaka. The 1.5" roller works well for good top speed on the 40cc but not wit the 32cc. I'd stick with the 1.25" on the 32cc & have even considered putting the 1.25" onto the 40cc. I'm running a 1.5" v-belt pulley now on the 32cc with a final drive ratio of 15.6:1 & its about right...just waiting on it to break in to go WOT...

Sounds right. I ran the 1" roller for break in. The 32cc likes the 1" a lot, but makes do with the 1.25. It's good enough for me, but the 40 would be sweet.

HappyCS,
I'd really like to get my hands on a 47cc Tanaka but cant seem to find them anywhere.
The 40cc is sweet & definitely has more power than the 32cc, but I like the quieter tone that the 32cc makes.
The 40cc sounds like a loud backpack blower. You know of any sources for Tanaka's on the CS pricing plan?

I don't know anywhere to get Tanakas for special rates, but I lucked out on one from Amazon, when it was some kind of equipment manufacturer's overstock and pawned off for $89 with no warranty.

Maybe there is somewhere to get in with someone buying TKs in bulk and order one off them.
Or just keep scouring Amazon and Ebay.

The only other thing I can think of is possibly buying a refurbished lawn equipment with the motor you want.

Here is Big Sky Tool offering a PF 3300 for $115, marked out of stock currently. (reconditioned)

You can look on Tanaka's page or call a go-ped dealer and find out what models of Tanakas are 30+ cc and have the right clutch for MABs. I know they sell a couple "utility" engines in the 30-45cc range, that probably have more guts than the Purefire ones. The PFs only have a 7:1 or 8:1 compression and carbs for fuel savings.

Here is something that uses a Tanaka 47cc engine. Maybe you can find a used or refurbished one. I bet if you can get in good with a really busy authorized service center somewhere (mower shop) you can probably buy one off them.

You can find the 65cc (4 1/2 hp) backpack blowers for around $400, reconditioned. The parts diagram shows a "flywheel assembly" where a clutch might be, so I don't know if you can fit a Tanaka clutch on there instead, or even better, fix it directly to an axle or clutch drum. http://bigskytool.com/productv2.aspx?id=2320&source=Froogle&gclid=CO_ntr6Go7ICFWd-TAodLUMA2g

HappyCS,
Thanks for all the info.
I too scored a Tanaka PF-3300 on Amazon while they were available for $89. (Only wish I bought a few more)
I got my Tanaka PF-4000 on eBay for under $200 brand new but they only were selling one.
I check eBay & Amazon daily for specials but they are very hard to come by.
I'm good to go for now with the two Tanaka's on 2 MB's, but always searching...lol
