    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)

    Tanaka 35cc utility new: $265, free shipping US48

    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

    That looks like a really fun motorbike.

    I've been in the garage alot these past two days since I decided to switch engines from one bike to the other.
    Now the Rocky Mountain RM7 has the Tanaka 40cc on the front & The Banshee Scream has the 32cc Tanaka on the back.
    I'll end up riding the Rocky Mtn more often as my daily commuter & the 40cc has a bit more power especially coupled to the low friction v-belt drive. It also perfectly matches the color scheme of the bike (Black/Orange).
    Will get some new pics & upload them soon.

    Swapped engines back again. I like the way these engines run mounted normal style instead of rotated gas cap up high.

    How did they run differently, or is it just a difference in the position of the tank neck and the pull starter?

    happycheapskate,
    I remember reading on here yesars ago that flipped to the cylinder sideways position causes a richer mixture somehow. It was one of Bamabike's posts & he was building mB's, riding mB's, & selling them. I've mounted 3 Tanaka's both ways with & without the expansion chamber exhausts & get a better running engine in the normal, cylinder up position. Also filling the Tanaka 40 while out on the road was a bear with the cylinder sideways. I dont carry a funnel & it was needed. I would rest the front wheel against a curb turned fully to the right & hold the right handlebar grip while laying the bike all the way over on its left side & would still spill some fuel...lol
    Sticking with the traditional position...

    Thanks for the info. It's possible that having the carb on top of the engine let air passing over the carburetor create a slight vacuum, which would make for the richer mixture.

    I like having the 1 gallon tank. When it gets down below 40%, I just add oil from a little bottle I carry, and gas it up at any filling station.

    I did over 100 miles today on the MB using it for work purposes. I carried 4 MSR bottles each holding 20 oz. & have some fuel left in the tank. I ordered 2 more larger MSR 30 oz bottles to carry on my lower fork legs with the Two Fish quick cage adaptors & 2 Profile bottle cages...Will post some pics when the 30 oz bottles arrive (now got the 20's in there)...I too carry small glass vials full of oil to make 20 oz of emergency fuel.

    I got the bottles full of pancake syrup from Cracker Barrel. haha. They are 1.5 oz each and sure were tasty (maple syrup). Then I just soaked them with pine sol and water and put 2 stroke oil in them for my cargo box.

    HCS,
    I love Cracker Barrel...So glad they just opened up a new one near my home.
    Thats a good idea re-using the syrup bottles.
    I bought 5 of these on eBay for a few bucks made of glass w/a nice seal in the cap.
