skyhawk in frame tank racer build

Hi everyone, ive had this baby for about half a year now and finally decided to make a build thread for it. It was a tough job building a bicycle from scratch as it gives you many choices to pick from. As If the frame wasnt crazy enough, i went ahead and put mountain biking rated forks on the front with a disc brake, and had a hayday with fitting disc brakes on the rear, but i succeded with thousanths of an inch to spare. i shoved a racing 2 stroke motor in it with porting, high compression, a mikuni carb, and a racing exhaust. Ive invested some serious bread in this build because its my hobby and my toys bring me joy. I love to talk about my bike and could all day, as ive modified and replaced every part on the bike, even in the motor. Please ask questions, ill be posting pictures as i find them

new mods

so i decided to get the 12 volt generator a friend had, and had fun blowing the 6 volt main bulb out of my headlight lol. i had a 12v led headlight to sauter in anyway and dang its bright.
i also got rid of my knobby tire in back, i have a flat tread now, its awesome

this thing is defiently a race bike it eats magneto coils like theyre candy, 1 a week lol. they cant take the speed lol. then again 10000 rpms is a bit much...

What is that extra piece in there ?

thats the 12v generator that i said i added. it goes inside the case on the oppisite side of the magneto

sub'd.............awesome build. I will have many questions after my head stops spinning.

you can put epoxy on either side of the coil (where the arrows point to) to improve it's life

so its been a while since ive been on here last. i live in illinois so i had all winter to rip down the motor and throw in fresh rings, bearings, and gaskets. ive managed to talk to and convince bert to become my go to parts guy and im very satisfied with the products. all that is left to do is re jet the carb, because i run lean at the top end and i feel it could go even faster with more fuel flow. this is a pic of it after 5 months of sitting, it was smokey lol

so im changing a couple things, im going to put a layback seat post on my bike,and im switching my drive sprocket from a 34 to a 30 tooth. i dont want to run my engine as hard going fast

 

[mikemarley]

disaster struck, locked up the chain at 50 and destroyed the case. the cause was my 11 tooth sprocket, im going back to 10. i also switched to a 30 tooth sprocket and put a replacement half case on. i only have the one case piece and studs left of my original gt5

Hope you get parts to fix..... I had a similar problem and I'm debating wether to buy a bottom end or buy a new kit...... It's not much more for a boat load of extra parts
