What is your favorite 35cc engine?

Original clutch!?! You suppose the Mitsy clutch would fit a PF4000?
I wonder where I could order one? At one point I tried to get a TLE 43,
but could not find one for sale anywhere.

The heavy duty clutch shoe uses the same part number for the Tanaka and Mitsu on the Staton site.
The attached picture is for the stock replacements for you to compare. it's almost impossible to locate a TLE-43. i lucked out and found my spare (John Deere badged) on a powerboard.

I see the 43 clutch looks substantially thicker, appears that it would
fit in a PF4000. By by the way I did another search on the Mitsu.
they're available thru Alibaba for $329. It says they are Japanese
made & not clones. I wasn't aware that the Mitsu was only 1.67
hp. Still it has an edge over the suby & gx35 in that it has a wider
band of rpm & better acceleration.

those links on alibaba will send you to the Staton site. no longer available.
the only Mitsubishi small engine still available in the states would be the TU-43.
Heard the TU-43 were still made in Japan but are not CARB compliant but I may be wrong.
Seen some places refer to the TLE-43 as 1.7 HP and others as 2.2 HP.
mine may be the 1.7 HP due to the fuel consumption rate but it accelerates like a 2.2 HP.
Wished i could get a HP carb mounted so I can use an expansion pipe but from what i've read it involves too much work and probably ill-advised.

Oh well, just took a ride with the PF4000, It's a bit loud, but adequate.
wish I could get more than 1000 mi to a clutch. I've been more tender
with it of late. Maybe I'll get 1400?

rawly, i'm curious as to what type of setup you are currently running that you are only getting 1000 - 1400 miles on your clutch. do you haul around a lot of weight? I love the brute power of the PF-4000 but the sound level with the stock exhaust is too loud for me. every time i have mine mounted on the GEBE and am stopped at the light, a car or motorcycle always wants to race me because the PF-4000 sounds so aggressive! i'm currently building up a performance MAB with the Tanaka 47R and an expansion pipe. the sound level makes it impossible to test the rig out on my neighborhood streets without annoying someone.

I was running a DIY belt drive at 29 to 1. I think the big
sheave just had to much leverage against the clutch drum.
As the rainy season is ending, I've gone to a friction setup
and am pedaling up to speed more before hitting the throttle.
I think that will help, but lots of stop & go is still hard on
clutches. So is 6'3", 250 + lots of hills.
Right now I"m pedaling a lot more than using a motored bike.
I lucked out & scored a really excellent bike at an absurdly
low price on CL. I was on my way home with it 1 hr. after
it posted. I can actually pedal it faster than the top spd.
of my friction setup.

with your gearing, weight, hills, and stop / go riding habit, i think 1300 miles is pretty decent on your clutch. i love my friction drive bikes but every engine i own has to work too hard with my 1.50" spindle on all of the steep hills on my commute route. i need to read up on your DIY belt drive bike. i've read about the guy that made a drive ring out of a bike rim attached to his rear wheel and want to try a similar setup.

 

[rawly old]

I'm the guy. I've done it using the rim of a 20" whl & 24" wheel.
both worked pretty well, but it took a lot of tension on the belt
which is what cooked clutches pretty quickly. I did it cuz it's
wet here 6/7 mos. a year. With oily, mossy roads friction just
can't perform well. For now my friction kit is fine 'til October?
The modifications I've made to my little lightweight road bike
make good all the time, road or trail. I took it out today on
a route I usually motor. I'm pretty stiff right now ,but my
computer showed it took only slightly longer, about 1.4
mph slower. I don't care that much about speed; if I did,
I'd have a motorcycle. I rarely even get up to 20 mph.
