chain tensioner / guide and new chain seemed to do the trick.

built another minibike so we could run around town on them without taking the ridic go kart, its crazy fast... and the cops don't seem to mind the mini bikes not sure if blasting down the roads on a insane go kart would be the same leniency lol

its a azusa kit and it def isn't as nice and put together as a gopowersports kit.

but its cool, i didn't want something the same

it keeps throwing the chain i bought a chain roller guide/tensioner for it, hasn't came yet. the frame isn't aligned perfectly or the sprocket is bent... lol

i can fix by moving the rear axle mount a little bit, or hopefully just this tensioner will stop it from coming off. i guess a lot of these old skool style frames dont' do well with 7.5hp motors when they were designed for 3hp. the frame can twist and throw the chain, and this one comes off randomly when you really give it a lot of gas

they also forgot to send the grips & throttle & throttle cable. i had to buy some expensive ones from the local motorcycle shop lol

i ran the CVT for a while, its a cheap chinese one and it didnt seem to work right. i had it lined up perfectly and it kept shredding belts so i took it off.

the low end torque was cool but it robbed a noticeable amount of power

when you run the cvt you have to put a riser plate on the engine to make room, it makes the stock muffler hit the frame so i was running it without a heat shield.

i didnt want to remove the riser so i could go back and forth if i wanted to i cut and rewelded the muffler so i could run the heat shield.

i have a little motorcycle muffler and some 1" exhaust pipe i might make a exhaust for it today

looks cool

I like this look, give me old skool vibes 

I'm worried my math maybe wrong:
d15b2 block has crower rods and vitara pistons and block decked 0.080" (about 2mm) so block is 205mm tall.
Head surfaced 0.010" or 0.254mm
Delta 272-2 cam is y8 based cam.

I advance cam 4.5 deg
Looking at https://www.d-series.org/threads/ignition-timing-cam-gear-timing-timing-belt.14790/ post #11



I advance cam 5 to 8 degs
I'm using y8 crank pulley and a z6 based adjustable cam gear.
I also adjust cam gear to y8 zero since vtec head on d15 block use a y8 cam gear to correct.
Eye balled using a y8 gear over the adj gear with cam gear center bolt out to line up keyway.
Then I mad the above adjustments, and the engine still cranks and no start.
So now I'm questioning my degree math.
Valve lash has been checked
I'm getting spark, fuel and compression but the timing events seems slightly off.
I was seeing a low vac reading from map at -4" hg, but advance the cam in 10deg territory and was seeing -9" hg now.
This is a fresh engine never been ran

So is my math for timing off?
Anybody got ideas?
Oh and another thing these posts talking about advancing and retarding is always in degrees on adjustable gear. As in 1 tic mar is 1 deg or do they mean 1 tic mark is 2 degs?

After several iterations of the wide body shapes, I came to the conclusion that the truck just isn't wide enough for the look I'm after. I went back to steel flares but a different shape than the old ones to make sure they clear the tires, they're an inch wider and 2" shorter. There's a lot of finish work left to make them seamless but I'm loving the look.

It's awesome new motor should be here tomorrow and I got a CVT "torque converter" for it

The tank was shaking a lot so I added some rubber washers in there

Thats lookin awesome.

It's pretty fun. New motor will be here in a few days
