Don't know, not sure what a stock one looks like. Connectors certainly aren 't OEM, so I'm guessing you have a kit loom. Would be surprised if the box is standard given the rest of the bike. What does it rev to ?

Hmmm, the tach has been a bit all over the place and I don't have a copy of the dyno run, but I think it was pulling well past 12500.

Being the kit bits guru ( I bet you're starting to regret this a bit now!!) the bike has kit Marvics and I need spare rims for wets, stockers would be fine as I doubt I'll find a set of Marvics anyway, but I can't find so far any stock rims Kawa or otherwise that come vaguely close to the same disc offsets etc - any experience in matching this kind of thing up???

The outside of your igniter appears different to the stock boxes, so I'd say pretty likely not standard as Brian wrote.

Just be mindful of the raised / removed rev limiters on kit or after market igniters such as Vance and Hines or the like. Our ZXRs produce good power high in the rev range, but will only play nicely up to a point. Rods can start poking out of places they aren't meant to when revved too high!

As an aside, I have played with a variety of igniters at different times (kit, OEM and Vance and Hines) - and of course it is subject to your cam timing etc, but I actually have got the most stable AFR through the rev range and highest hp output with the OEM igniter.

I think you will have a tough time sourcing a suitable pair of rims for wets. I haven't got too much advice to help with your search I'm afraid...

My solution is running ZXR forks with the Marvics. Machined up spacers to fit. Had discs made to match up offset of front calipers and rear caliper position. Allows easy interchange with stock rims, but a major pain to get everything done. Not a quick solution. You could consider going down this path, but would obviously mean the removal of your current forks.

Discarding the stock ZXR fork internals and replacing with Ohlins internals, you can get a very good feel with excellent adjustability. So, this is not a bad option. Biggest difference is the physical look - ie they look like standard OEM forks.

...or train your mates, spouse, kid/s to become master tyre changers, take them with you to every meeting / track day that you attend and click your fingers when you want to change from slicks to wets or vice versa! :lol:

Ha, that sounds like a recipe for disaster! I lost a championship once because I left it too late to change tyres and that was with spare rims!

Interesting on the OEM igniter. The other thing with mine is that it has Franks triple clamps so they may be set a little wider than stock and with the WP forks, could be some ways off normal dims - it certainly has some deep spacers on the front.

I must say that so far, the front end and the whole chassis set up feels great to me although I've not been at race pace on it.

I think wheels are pretty much a case of using whatever you can find. I know that there were kit wheels, but I think the only thing that differentiated them from off-the-shelf Marvics was the disc pattern.

Hey mate I had a look at this bike when it was for sale recently in S.A. If you have old AMCN's you will see that it is in the for sale section up the back in a few of the old issues, the ISR's and WP, Marvic gear is the giveaway. As for the swingarm, Robbie Phillis' bike ran one just like that, you can see it clearly in the poster they put in the middle of one issue with the cute brunette on the back. If you look in Rob's pics on facebook you'll also see the ZXR M1 with the braced swingarm quite clearly.

Chris,

Thanks for the info - do you mean the famous Susie Moroney (?) pic on the Zurich bike? I thought that was Mladins 91 bike but I've got the mag somewhere so I'll dig it out. And do you know the issues or approx dates the ad was seen in?? I should have those issues too. I went back through a load of my old mags but couldn't see a pic of this bike in any race reports which made me think it was either back in the field or run at club/state level only. Also, as others here have indicated, it might have been built by Shaun Sutcliffe ex TKA from team parts so maybe didn't race as a complete bike as such in the day but some of the parts may have, if that makes sense. I know it was run by a local team in Vic called SRT at some point, I'm guessing late 90's. Do you know any more on it??

Hey mate Sue Ellen Underwood (Susie) is with Mladin's bike (K1-K2) you are correct. I'm referring to a later issue the following year though where they have Robbie Phillis's M1 and in that poster you can see the braced swingarm like yours. The following year they did a poster with Marty Cragill's privateer bike and the very gorgeous blonde Sarah Jane and you can also see the braced swingarm there..............there's a bit of a pattern forming here with me collecting girlie on ZXR posters hey!! If you have facebook check Rob Phillis photos, there's a couple of pics of his M1 there. I will happily stand corrected here, but when Rob moved from WSB back to Australian superbikes evidently Kawasaki gave him some trick parts in recognition of his service in the world arena and I believe there were ohlins forks, braced swingarm etc, so if you have ex-TKA parts it may be possible that's your swingarm?! Kit swingarms I have seen recently sell overseas were not braced like yours. Good luck with the build mate, please keep us informed :-)

Thanks Chris, I have most of the AMCN's from that time so will get digging. But what month/year approx was the ad you mentioned?? I'm assuming must be a few years later?

I saw the pic you put on ZXforums of the Phillis bike in the pit lane at Eastern Creek (with Ricky Rice in the background??) its looks identical, I guess the question then is how many of these swingarms ended up in circulation.

I'm a bit skint at the moment so bike progress is slow plus i have a 250GP bike to get out, but as it is the ZXR is not far off being race ready so I hope to do a bit of club stuff here in Vic through the year. The way its looking it won't be for a few months yet.

I spoke to Shaun about it and over the phone it was sounding like the one he built for his brother, although he said that didn't have ISR's and had different triples, and after I sent him pics he suggested it may in fact be a bike that Chris Hill had - anybody have a contact for him??

Re: ZXR 750 M frame and engine nos

Chris, is this the ad you meant?? I noticed that the seller, Steven Baxter, teamed up with Chris Hill for I think a 6hr at PI on an RC30 which at least links them and therefore possibly to my bike. On the down side I have a few pics of Chris Hill on a ZXR and its not my bike, its the earlier j/k model. Also found this interesting article on Phillis's ZXR, reason this is of interest is it has the same swingarm as mine, the only pics anywhere I have found of the same. The article mentions its a factory swingarm. Mine is cut down a bit at the front of the larger vertical spar which either means they trimmed it for a reason (what?) or someone's had a go at copying the bracing onto a std swingarm. Looking at the welds the latter may be the case but I'm no welder so dunno, just looks a little haphazard to me.

Got a pic of the swingarm work you're referring to ?

Just an I observation; those welds look pretty rough!

Ah yes, the swingarm has been channeled. That was a reasonable common mod overseas, although I didn't realise that anyone had done it locally. All due to thr swingarm pivot position, a higher pivot means the chain pulls directly down on the swingarm, so by cutting the arm, the chain gets a clear run and doesnm't apply as much pro-squat (I think) to the swingarm.

Cheers,
Brian
