Had a bit of a cleaning session aswell...engine responded well to a good dose of gunk and I also had a go at the downpipes with some brasso

Tidy job Red, just what i used....brasso & elbow grease & no gimmicks.....& it really works

Hi nog...pictures make  them look better than they are......more time needed

Damn. I was hoping to bring my bike to yours so you could show (do) mine

Certainly an inventive fix... I would probably have attempt to remove the stud and made more of a mess

[red98]

going to leave the engine painting untill the warmer weather comes,then i`ll probs drill the stud out and fit stainless studs and nuts.....this fix took minutes and was easy to do,my mot is due so going to sort that first as dont want the bike off the road with better weather just around the corner

Bit slow at work today so took my downpipes in and finished polishing them up.....pipes back on the bike, second picture shows whats visable of my stud repair.....happy with that

Mine were that bad there was no way that they were going to come out of the ports without a bit of persuasion, like a disc cutter and a lump hammer.

[red98]

you did well getting them off without breaking any studs......mine were stuck in the ports aswell,took about 20 mins to free off........i wonder if this is going to be a problem with the thou.....unlike the 600 the tops of the downpipes are well hidden behind the radiator,no need to remove the rad on the 600`s to get them off...

when I replaced my studs I bought mine from a Vauxhall dealer, they were nearly half the price of Yamaha ones and the same size, I bought some stainless steel dome head nuts off eBay so the water cannot get into the end of the studs again,

here is a pic of the top of my downpipes


and here is a pic of the "new" set of downpipes with the nuts,

Dunno if I've mentioned this before but the finest penetrating fluid known to man is a 50/50 mix of ATF and thinners or white spirit.
Just thought I would mention it.
