Default honda 100 cc build

here is my build, a honda 100cc motor and a tork a verter, comet tav2, first i used angle iron 1 1/2" and 1" flat iron to make my motor mount bracketas in pic1, then 4 bolts to add the tav2, pic2 you need a lot of room on the bike framee to add this, i used the giant bike frame, added a rear hub for disk brakes on the tire, see my other post, on the net i found spacers to make my 5/8 shaft into a 3/4 inch shaft, i needed 3 of these to make the tav2 clutch work on the honda, pic3, pic 4 shows the clearence of the back of the tav2 crank and the motor is bolted in place,pic 5 sory didnt turn out, but everything is bolted together and ready for test drive, final pic is the finished bike with the tav2 finished... the mini bike seat on the back is my sons seat, he goes everyware with me...
i have 2 guide wheels on the chain, the lower one is modified with a tention spring, this setup works perfect, whe guide wheels are from the doodlebug mini bike, this has a very fast take off speed, i have ben cruising at about 45mph. and have not tried full throtel yet, this verriable speed cloutch setup has a overdrive, i have a 60 point rear sprocket on the back tire, i am very happy with this setup, i will be driving the bike from minnesota to florida in june, happy biking all... captian roger

I love it! That is a great four stroke build.

Wow Capy! Awesome build. I have to get on another PC 'cause I cant see your pics well. Sid note, I make engine mounts about the same way. Like em way more then the Hoot or other stuff. I used alum flat stock for the up bends and not failed but did allow engine to tip a wee bit.

Can you still find tork o verters? I waited for months and finally asked for my money back.

Again, great build and thanks for posting.

I noticed the 10 tooth kit had a 40/41 pitch will this work with a 415 or 410 chain? I know my sprocket is for 415 Chain and 45T, so I think the 10T would work nicely. Just need a second opinion on the chain size, so confusing!!!

What was the manufacturer of the spacer you bought? Could you provide a link?

Is there any particular reason you went with the Torq-A-Verter versus EZ Q-matic drive?

40/41 sprockets are too thick for 415/410 chain. 41 chain will work well on 410/415 sprockets.
