just wanted to say hi. my name is tom..
i have a yamaha kt100 superdyne racing bluenprinted race engine , currently it not in working mode but it will soon
the culprit and reasons why my kart is down is that i overheated my horstman triple disc dry clutch, but now i got the clutch rebuilt ,and this is where the problem started.

how do i install the clutch..is there a diy tutorial somewhere on how to install the clutch.. i dont feel comfortable doing it my self without a tutorial...

it need a new clutch install
need new spark plug
need new starter nuts
need to bleed the brake.

I don't know Horstman from Shinola, but I'm going to go with, place clutch on output shaft, replace nut, tighten.

simple as that ?? no balance or anything ?? like must be no precautious ??

Or the old standby--install in the reverse order of disassembly.

Oh, and one more thing:

nghianevo · Dec 9, 2016

hahah thanks guys.. well i got the karts and i inspected evrything...and it funny how even the manual said that to lappi g the clutch into the shalf..and insert the woodruff keys.. which it wierd.. because i searched my shaft dosnt have a key joints for the woodruff keys and therefore i dotn think i need it..
but i need to lapping the clutch which j have no idea what it is... i also have a new starter nuts too

now i also need a spark plug.. and i cant seems to find which car or cross reference to BKR10EIX SPARK PLUG
anyone knows what car cross reference with yamaha kt100 spark plugs ?

nghianevo · Dec 9, 2016

this is my kart kt100s superdyne racing engine

anderkart · Dec 10, 2016

Here's a link to a NGK cross reference chart: http://www.angelfire.com/extreme4/skidoolympique/SPARK_PLUG_CROSS_REFERENCE.htm

But I'd sugest you buy the exact same brand/part number plugs Superdyne instaled when they blueprinted your engine. If your auto parts store doesnt have them in stock, they could probably specal order them in just a few days.

This video exsplanes how to lap any type of tapered shaft, like your kt100 has:

i will do the lapping compound tonight.. now...by the way... the shalf on my kt100.. it doesnt have a slot for the wood ruff keys...but my horstman clutch does... what give.... so can i just install it without the wood ruff keys ?

Rail rider · Dec 16, 2016

Is the shaft a 9/16 tapered on your engine?

anderkart · Dec 17, 2016

Looks like Horstmen HDC-5CP triple disc dry clutch info recommends tightening the nut to 350 inch pounds. (that converts to 29 foot pounds if you don't have an inch pound torque wrench)

nghianevo · Dec 19, 2016

rail.... yes..it a 9/16 tapered ..i inspected the kart closely and my clutch and it does have a little half moon on the shalf... and my clutch also have a groove for the wood ruff keys ... so i ordered just the wood ruff keys to amke sure i did it right ...

@anderkart... yes it is a horstman dry clutch HDC 5CP triple disc clutch....that awesome that u know what my clutch is... i love that clutch... it grab so awesome... i however overheated my clutch as i keep braking and not enought full WOT to cool it down.... secondly .... and yes i dont have an inch pound wrench... so i just do it to 29 then... or 30 to be safe... now... do i tighten the clutch with the nut and then lapping it.. or do i just leave the clutch out.. but ima use the keys just to be safe... ..

will pick up spark plug tonight..and insert that...
will take the tank out and clean it with new gas...
will be lapping the compound in the shalf tonight
and then wait for the wood ruff keys to be here and then install the clutch...

Yep, just remount it ... No balancing needed. I had a **** of a tyme finding one of those for my margay cheetah with a 100cc McColloch. Edit...But, but, but, **** is in the Bible. We can't censor ****.

RIGHHHHT....You just get banned for using non-censored words! (...or at least shouldn't be censored words.)

I got banned for a month for a thread I started showing common acceptable words only become cuss words when used in a different context.

nghianevo · Dec 19, 2016

lol thanks guys im so confused right now on hownto bleed the brake .. so some poeple said get a water bottle make the hole thru the cap.. then run a thbr thru the bleeder valve near the brake disc and keep pumping ?.... but then where do i insert brake fluid

Poboy kartman · Dec 19, 2016

Wear r u located? Because you post like you have a limited knowledge of the English language.

Rail rider · Dec 19, 2016

Add the brake fluid into your master cylinder it's the little boxy thing that is connected to your peddle or a rod coming off the peddle. Careful with those screws they like to strip out.
