What about the engine centercase treatment? Buffing / painting?

The crank cases are petrol washed for almost 2 hours ,not buffed or painted .
After washing the crank cases are as good as new.

, also which swing arm are you using, is it from gladiator, your bike is pretty much complete and that makes it a very good starting point , as for the cylinder second hand cylinders go for about 2-2.5k here better you go for a new one ,as you will need to purchase a new piston and rebore to next oversize which will add around 750-1000 on top of the purchase price and with the local rebore job there is no guarantee how long it will last , if possible go for new block kit , it will be expensive but will give you peace of mind

Thanks for the help kb 100, the bore is a non sleeved one

0.50 mm size ,my mech told to change the piston rings only and it would be fine .

Yes sathish , gave the chassis,swing arm,2 numbers of L brackets,center stand,side stand and headlight stays for powder coating and also the nuts and bolts for zinc dip(except some which would be given for chroming while giving the silencer) and no updates as of now .will start after getting the powder coated parts

Hello naren,after powder coating the chassis, use clear coat also as it will give deep lustrous shine to the frame of the bike and what is the charge of powder coating.

Hi kusmaker , is the clear coat can be done after some time or should be done just after the powder coating and if possible can you post some pics of powder coated parts after clear coating . As for the price for powder coating i dont know the price yet as i didnt checked with the powder coating guy and it will take another 3 to 4 days to get them i think

.will let you the price after getting them

No naren , clear coat is applied just after the paint is baked, the frame is cleaned with high pressure water, and then clear coat is applied and again baked for about half an hour, i can't post pictures because the bike is already assembled, but me and my friend have just done this treatment process to my friends rxg bike recently, the whole process e.g. acid wash, phosphating, two coats of powder coat plus two coats of clear costed us 5000/-rs, but the outcome was brilliant the frame was shining like glass.

you shouldnt have acid washed a chassis man , acid baths eats into metal decreasing the thickness of the pipe weakening the chassis ,also if not properly cleaned the acid residue left in hard to teach places (inside the tubes) will lead to further serious corossion, btw how long was it dipped in the acid bath

Re: Yamaha Rxz 4 Speed Restoration ( Help Needed)

You are right kb, initially we were looking for sand blasting, but we didn't find any at our nearby place, the chassis was badly rusted, so we did took the risk of giving her an acid bath, and moreover we were having the facility of acid bath,phosphating and powder coating at the same facility, total time was 45min, afaik, because we left the frame there, and the owner told us that the chassis will be dipped for 45min, after the acid wash chassis was washed properly with high pressure water, is there any other way beside acid wash and sand blasting to clean the frame.

if its just paint you can try paint stripper, also wirebrush mounted on an angle grinder will obliterate rust in no time, btw 45min in acid bath for a 2wheeler chasis is too much

pS: should have gone for a new chassis costs only 3.2k

**kusmaker** · 04-09-2014, 08:55 AM

Re: Yamaha Rxz 4 Speed Restoration ( Help Needed)

Let's keep our finger crossed,and pray,option of using paint stripper never came into our mind probably because the amount of heavy rust that was on the frame,but thank's for these two methods you have mentioned,will keep them in mind for future, yes we could have gone for a new chassis but then you have to reregister the new chassis no. on the RC. and my friend was not willing to do that.

Need not be.
New chassis comes without Chassis number punching. You can get the old number punched in new frame (no hassle with RTO / RC)

Re: Yamaha Rxz 4 Speed Restoration ( Help Needed)

Ok we didn't knew this thing, otherwise we had not taken so much of headache and wouldn't have spended so much of money on powder coating. Thank's for the information.
