after some chaos i finally got my bike running. after some top speed runs and cruising i looked down and saw a **** ton of what i thought was smoke. it ended up being one of the water hoses that melted open, letting the water touch the hot pipe. when i got it back home it was hissing and bubbling like crazy. the exhaust pipe melted thru the hose. it eventually melts close after the pipe cools.





do you think auto parts store would have something similar to this hose that i could replace. also my friends father does custom motorcycles and one of his bikes has wrap on the exhaust tubing. do you think i could use some where the hose is close to the exhaust pipe. i would rather go this route rather than trying to bend the pipe around the hose. i'd probably jack it up and restrict the exhaust even more. while the pipe is off i'll probably do the mod where u remove the ****ty welds.

edit: the hose isn't touching the pipe, more like 1/8 inch away from it.

Can you cut alittle hose off the long straight part and pull it away from the pipe more. It's real close to your spark plug wire too. Crinkled up alum foil to disapate the heat, or pipe wrap which is not cheap.

Put heatwrap on the exhaust pipe..............





The best way to do the wrap is to sand and paint the pipe with heat resistant paint,,,

cure the paint,,,

dip the wrap in warm water so it wraps nice and tight,,,

use tywire to secure the wrap to the pipe and at the headder connection

if youre using 1" wrap ,,wrap the pipe overrlapped 1/2",,,If using 1 1/2" wrap 3/4 overlap and 2"@1" overlap......

Then after the heatwrap dries,,,paint the heatwrap with the heat resistant paint aswell......

epr, the hose attaches onto the metal piece that leaves it very close to the pipe, im sure i could cut some but it would still leave some near it.

dang cam that wrap looks sick. did you order your wrap online? because the one shop i checked with said it had to be special ordered. How many feet of wrap did you use?

and for the hose i think it has a small hole in it that leaks VERY little, i'd still like to replace it. where do you supose i could get the part. i think i could use a generic straight hose then cut it to fit.

Thanks alot,,,I ordered the wrap online....I got it from ebay...I bought a 25ft roll

This site suggests you install this one dry...I got a different roll...mine had no ties...

The rubber hose....Take it off and go to your local autoparts store and see if they can match one close.....dont say pocketbike either....."watercooled generator"......

good tip, so after the wrap is done and the new hose is in, how hot does the outside of the wrap get? can you hold your hand to it?. basically what im saying is, after the wrap, it will touch the hose. it should be okay yeah?

edit: and did you use the whole roll? how many feet did you have left over?

Yes U can hold your hand to it but after a hard run not for very long but if you touched the bare pipe your fingertips would smell like burnt chicken...

Turbo engines get hot at the flange....Thats why theres an intercooler...to cool the air because even on the charge side of the turbo the air heats up because of the ceramic turbo fan acting like a heatsink and from the super heated flange......The heatwrap keeps the heat from building up in unwanted areas aswell as has other benefits...

On my hotrod engines the ignition wire can lay against a wrapped headder without burning through.........It lowers the heat build-up under the hood too and under the floorboards where the headders go under...

1 roll did two bikes..........X15 and X22...Pictured below is the x22...the center has an expansion pipe




This was done for numerous reasons on this model......It definately added to the way it performed as a full auto bike....My friend Paully who bought it was toasting his neighbor who was riding an 81 pe175 stopsign to stopsign...The guy on the PE was ****ed....LOL

im about to head down to autozone and special order this if its any good

http://www.autozone.com/autozone/ac...ting-wrap/_/N-269j?itemIdentifier=398787_0_0_

what do you think? im sure 15 feet could do my pipe fine

ill go to harbor freight and pick up some of those hose clamps you screw tight to hold the wrap on near the exhaust manifold and the back near the muffler. they would work good to hold it?

The wrap you picked is good....at the autoparts store on the HELP aisle they have stainless ty-wire.....Use that,,,,,

If you look in the lower left corner I used both and kept my pipe as a two piece removeable still............I use the tywire at the flange aswell

ok just special ordered the wrap($10.73 after tax), went to home depot to pick up the dremel bit (i hope its long enough) the hi temp paint and the rebar ties. all for a little over 20 bucks



the ties came in a bag of 100 and were 2 bucks cheaper than the big roll of wire, why not im only going to use a few lol

edit: if the ties dont work ill use some hose clamps :)

You can put 2 or 3 strips together to make longer ones, had to do that on my C1 gas tank to hold it to the frame. Old rubber bike or car inner tubes cut up make great mounts all over the bike Strips under the tank and seat and tank cover to frame help keep it from rubbing or breaking the plastic. You can also buy 1/4" hole about 5/8" out side steel/rubber washers, for mounting the body to the frame, put two rubber parts together and you have an exh or motor mount.

Ouch...I forgot to tell ya about that dremel bit.............If you have a Sears Hardware store or True Value Store go there....$1.50 each and youcan get three 1" conical shaped grinding stones...Youll probably use 1 but they have otherr uses aswell......

That sloppy weld is the engines backpressure and powerkiller on an X15/19

The pipes looking good so far..............Keep up the good work...........

swung by autozone after class, picked up the wrap and some hose clamps, should be done by tonight :)



cam, the sears is like 10 miles away and the true value is even further, i'll probably just pick up another one or two from home depot(literally like 200 feet from my house). did you say 3 for 1.50? that might be worth the drive :D
