Yes that is the exact pipe Is it any different compared to the standard pipes

@mbmO8 Head’s still leaking bud. It’s probably best to replace the base/barrel gasket as well. Myself, I remove the studs from the barrel an lap the top in with a square of plate glass and some 240-ish wet and dry sand paper. Then do the same with the cylinder head. Just to remove the crap. Doing up the head nuts really needs a little 1/4 in drive torque wrench to get it right. I do it in three stages… I know that it’s no consolation but I’ve just had to put a newly rebored barrel and head on and had to go through all the fuxin hassle of it myself 🫤 …

I crawled around the bike today trying to locate where the clatter came from, paying extra attention to the powervalve cap. Holding a screwdriver against various covers to feel vibrations. I am far from certain, but I think it is the water pump, actually. I might disassemble that and have a look later this week. Thank you both for the input!

The Mikuni 28mm that is fitted from factory is a very good and serviceable unit. Before replacing it, it is well worth giving it a refurbishment first. They're also becoming like hens teeth and as such is well worth keeping ahold of. I ended up going with a 32mm Dellorto VHSA that's found on the same engine which is fitted to the TZR Belgarda.

@Stevie-Wonder Saw this on Facebook, well done buddy Those Diversions are great bikes, back in the day they had a reputation for being reliable and doing everything well.

Aww, that sounds sick. I live near the Forest of Dean which I imagine would be endless fun of cycling round there. But I've never been as I don't have anyway to transport push bikes over to there (40 ish mile). That does sound like hard work though, just keeping the bikes riding nicely

Replacement

Unable to log back in had to set up a new account

I have tried another CDI still no luck. No servo cycle and no spark. I have tried three different stators and same result. Because the replacement bits I .trying are second hand I have now way of knowing if they are ok. Is there a way to work through the bots one by one. For example can I connect the servo to the battery somehow to see if it works? I can turn it by hand so it's not seized. I don't understand why servo and coil not working. Please help.

Okay...so some overnight parts from Japan and CMSNL and some others from Australia I've finished the gearbox rebuild.....

This completes the output shaft rebuild.

[image: AP1GczNkYj3ORIWqQl0xC4kYfaZyJ1ywJV2dfvlihCnch34e7OrCJ1hJIc1Oh9EXyTvIBN8FWkZxZgKaWRp0BakEPsrsPAWWkLHEcPGATSnyyucBAsdvVx3W-xukLygatC3vIlJjx5vrvCrE_pRhpFoyG6KT=w1922-h928-s-no?authuser=0] Should go without saying, all near bearings and a lovely carbon fibre chain guard which I bought about 5 years ago for the Raptor. I'll probably keep the Raptor bone stock and therefore it's not needed for that project and can go onto this beasty. I did have some swinging arm spool spacers machined up but for the life of me I simply cannot find what I done with them. No doubt they'll turn up eventually.

@HOTSHOT-III No, I believe it's a Yamaha DT230 Lanza arm. But yes it's like half the weight of the original one I had. I just need to get the right parts machined up to fit my wheels etc. I've been so spent on 4/5 other very expensive projects that I just haven't bit the bullet yet to order the machine shop work. With regards to mudflap where, I'll probably design some sacrificial item in CAD and 3D print it. @RikuRo I've sent you various links. Any DTR from 1989-2004 will do.

@Challenger very nice build, may I ask which wheels these are and what size they are. I presume they also fit the dt125r swingarm and forks?

@somerandomguy314 Really? I am sure that's not the case, I sell to EU all the time through eBay's Global Shipping Programme. Ask the seller if they'd enable it, it's invisible to them and they just ship it to a UK Warehouse.
