All plastic from the fuel tank forward broken / Forks leaking... Check it hasn't had a front end smash, which means are the forks bent, radiator (if it has one) damaged, head of the frame damaged, wheel damage, front brake damage or handlebar damage. There's your first job!!!

Since it's a recent purchase, maybe it HAS been getting gradually worse for a while, hence the sale! lol

We shall await...

Worst come to worst, a cloth round it to protect the shaft and a pair of mole grips. Of course, if you can wiggle it around without that, then you know it's buggered!

On a bit of a rummage, what I'm getting is: Ignition coil (faulty ignition)...

To check the output shaft, it might be an idea to take the sprocket off and replace it with a bar with a hole in it (if you can manufacture such), it will give you more leverage for wiggling.

Shame you didn't show us the bottom of the chain too, but... Interesting sound! My guesses are: 1/ The chain is too tight. 2/ The chain is trashed (check stretch (doesn't matter how old it is, my Thunderace eats chains!)). 3/ You have a bearing well on the way out, it might be worth making sure you haven't missed a spacer and clamped the bearings down, check this diagram to make sure you have all the spacers in the wheel and in the right order: Yamaha YZF600R THUNDERCAT (4TVB, 2001) 070 A 2001 REAR WHEEL supplied next day (UK only) by Fowlers Parts The obvious answer would be the front sprocket shaft bearings: Yamaha YZF600R THUNDERCAT (4TVB, 2001) 070 A 2001 TRANSMISSION supplied next day (UK only) by Fowlers Parts 4/ As finnerz89 said above, check your chain guide isn't worn away... If it's nothing obvious, I'd get it into a garage for a checkup ASAP, whatever that is is either stupidly easy to fix or eating something (or both). And you don't want to leave it long enough for it to actually eat something!

You realise that's an eleven year old post?

It would be useful...

Even I've heard of these guys!

It looks like there may be a couple of hole options on the frame for the rear shock rocker to connect to, I'd check that out first. The other obvious option would be a lower seat. However, personally, I'd see how she goes with it first, remember, you kinda grow into bikes. As she relaxes she'll be able to get her feet down further...

Hi Bob, Always good to see the younger generation getting into bikes!

Yey!

Can they be sleeved?

A cylinder is a big thing, with many sides and holes. Where exactly is the fuel leaking from? Through the head gasket? Through the rocker gasket? Through the carb/cylinder union? There are not many places (or reasons) where fuel should ever be able to leak from, and you're not giving us much idea of which one it is. Do both cylinders have good compression? Seems a little rude, but that WAS the best mechanical advice... Only the bloke 'wot done it' will easily figure out what he's done. The second best mechanical advice in this case is: If you don't know about fuel systems, don't mess with them! Leave them to the professionals. If it was a professional that messed it up, then... If you're not going to take it back to him, a better professional would be a good idea rather than trying to tackle it by yourself (because, if YOU were a professional, you'd have done it yourself in the first place...). If (as an amateur) you do anything to this then you run the risk of making whatever he has messed up worse (or simply giving him the option to say 'you must have done that when you took it apart') and then it will cost you twice as much to have it fixed properly. If not caught (or a little less severe) you could have seen this problem on the road as all that great work on your bike went up in flames! And no body likes that idea..!!! Something isn't right here... You said the bike is currently in for paint. And that your painter buddy has 'done your carbs' because it's had a full strip down. You're not due to get it back for a fortnight (assumedly because it's still in paint), but you already know there's a problem with the fuel system, which means they've had the engine running? On a bench? But you're going to get them to give you it back early so that: You can fix it? Isn't this what they were supposed to be doing? What am I missing here? The timeline seems skewed somehow? Or is it just late..? The bottom line here is: We need much more information! 1/ Did it leak BEFORE he took it apart? 2/ The other cylinder doesn't leak, does it fire? 3/ Do you have good compression on both cylinders? 4/ If you've had fuel leaking into your cylinder from 'possibly' a badly done carb, have you blown the head gasket through hydraulic lock while turning it over? 5/ Have you got any fuel in your engine oil? 6/ Did you notice there was a New Members Welcome Area? 7/ Has the rest of the engine been stripped? 8/ Exactly how much fuel is leaking? 9/ Photos/Videos are good!!!

Ho Ho H... No, wait...

Good going! Looks great...

Ok, maybe next month I'll fork over some cash. Hopefully it's not just a scam and they just take my money! lol

I couldn't find a 'middle finger' emoji, so...

So you reckon those hoses look ok?

Probably as good as you could have expected..! 👍

I've seen them in both colours, and don't know whether there's a determinator that states which colour should be used. The obvious answer would be: What colour were they before you painted the parts?

Right, then did you contact them? Telling them that their posted information was incorrect and that their recommendation caused damage to your bike (showing proof (probably in the form of the bill and a covering letter from the garage))? If they ARE reputable, they will (at the very least) refund you for your purchase, and ideally do that AND compensate you for the repair bill...

What do you guys think about Chinese Parts in general? I'm looking at some silicone hoses: Silicone Radiator Hose Kit For 1993-98 Yamaha YZF750R 96-02 YZF1000R Thunderace | eBay I found a site that makes them in England, but they don't do them for the Thunderace (although they do do them for the Thundercat!!!). Do these look ok?
