giron ... to be honest the only flaw on my bike is the distance from the sprocket to swingarm, I think Alex's answer to incline the engine would be a better solution, but I also did not want to cut the chassis to much, not keen on some of the frame mods on a 3ma (kickstart area)

Not sure if you guys were aware, a couple of years ago I borrowed a supermono for a weekend on the Brands GP circuit, I destroyed the engine on the second outing.
My friend was very good about it, and would not let me pay for the rebuild.
Well, I got the opportunity to repay him, we decided to take the Big Blue Bus racing again (his nickname)
This time it was at snetterton 200 circuit.
The class entered was Blue Haze GPF (road derived two strokes)
On the Saturday we had a few issues, rider not quite understanding how a 500 makes power, he's a fast 125 rider, lucky enough a very jealous Jeremy (Brands rider) appeared and explained to Ben how to use the power/torgue and handling (yes it handles) , after taking his advice we won the first race class win, only beaten for the overall win by a TZ250 4DP by less than 1/10th, Ben (rider came in saying that he now needed a new name for the bus, he explained that he was overtaking people on the outside of bends where he really shouldnt be able to, saturday was the first time he rode the 500, 15 min practice that was not great and then a race, little bit a fettling and the bus was ready for the next race. This race we started in p2, alas by this time the clutch was starting to not be so happy ( same clutch since i built the bike) any way as he was enjoying himself he slackened off the clutch at the lever and all seemed well, so he lit it up and got the win. The noise coming down the straight in 6th from 15 foot away is something to behold. The sunday was a different situation, saturday night I spent a couple of hours going through the 500, after the clutch issue earlier I decided to change the oil, not good oil was burnt , we all know that smell, clutch wasnt long for this world, backed everything off , so at least we could have a go. On a plus finally happy with my carburation.
Weather was looking bleak, did the warm up lap no issues, unfortunately there was a problem with another bike on the line, so the start was delayed, engines still running, what seemed like an eternity, the race got away, my rider looked sluggish ? he past the pit wall a couple of times obviously slow and came in, telling me the clutch had given up. Fair enough, its done an awful lot i thought !
We decided to have a debrief (mutual piss taking) and analysed what had happened in the last race, ie clutch, it was at this point he told me he had been starting in 2nd as he didnt like first ? and was sitting on the line in gear, in fact he never selected neutral all weekend, he even left it in gear when he came in from track ? so the clutch issue was suddenly apparent, I asked 'why' 'why' 'why' , it turns out thats how he rides , never been a road rider. He was gutted as he wanted to beat Jeremy. On a side note 3 weeks later at brands on his R1 he was having start line issues, same thing again holding clutch keeping bike in gear, try to get a rider to change is a difficult thing !
The 4th race he went out on the 250 in absolutely diabolical conditions, I stood on the pit wall for the entire race , as crew chief mechanic owner etc I felt the need to be there, he was out there racing after all.
I needed to change clothes after and Ben was shaking with cold when he came in, couldnt see anything as the rain and spray was so much, Ben won this race beating many faster bikes, but the conditions helped.
So not a bad weekend the Bus now holds the class lap record and two firsts and a consolation win on the 250.

This year thats 4 wins and a lap record with two different riders at two different tracks in different conditions. ( fundementally flawed ...... my arse it is haha)

Im having another operation on the leg, but hoping to be fit enough to attend race school in February, like a fool I allowed my licence to slip, and I have to go through the whole process again, cant promise any more wins but I hope to get out at least once next year, maybe Brands GP :)

That is so good to read. I always figured the bike would do well.
I think we all knew there was nothing wrong 3MA based 500's.

125 rider started in 2nd gear - that makes 'sense' to me as the clutch slipping start would seem normal to him.
too bad

RC45 outside of an TZR250 3MA frame a TZ250 frame is better. The one with the carburetor up front. Don't want to start a war. I like to know how many TZR250 3MA frames have you build with an RZ500 engine? Now lets see Suheiro has build quite a few and Nigel as well

I am all in for a war - I love wars, especially on the Internet.

But first lets draw up the battle lines so I can understand who I am battling and what I am battling about.

From reading a number of your posts in this thread though, i am guessing you have completely missed my point and got hold of the wrong end of the stick. Wouldn't be the first time either.

So to clarify my position in this very hot topic of "Is the 3MA a suitable platform for the RZ500 engine" it is as follows:

I have always 100% supported using the 3MA as the best, most accessible, most suitable, easiest to work with, most stable and correctly dimension-ed chassis to support a V4 500 engine.

Now, who is it that we are going to war against to defend this position?

You may (or may not) have noticed that Dubsey has never objected to my sarcastic remarks about the unsuitability of the 3MA for the task at hand - in fact it was I that stepped up a couple years back and called out one of the custom chassis builders that criticized the 3MA chassis as not suited to task and as proof I presented the Blue Bus as evidence they where flat out wrong.

In fact just 2 or 3 posts up this page I said I have always known the 3MA is suited to the task - so I am not sure where you got the idea that I think otherwise.

As for the TZ250 3AK/3LC/3TC being suitable for the housing the 500 engine, uhm - I know that - I have such a hybrid under construction in my garage.

I saw an earlier posting where you said that the 3ma was the wrong frame. I didn't notice sarcasm. Go ahead and post your build with the TZ frame. You can bring the spark back to this site. It has gotten veryyyyyyyyyyyy boring

Hahaha

RC45 yes you have always understood the humour (are you english ?)

Giron it is a very english thing to be able to mock yourself, and I do constantly, and the bus

the sarcasm re 3ma's not working is in reference to a builder who knocked every 3ma build, so we just take the piss everytime another 3ma is completed or does well.

BTW, I think doing in a Supermono for an RZ500 clutch was a more than fair exchange LOL - if I am not mistaken Supermono's are sitting at about 5 or 6 x pristine stock RZ500 values these days, maybe more.

It was/is a tig craft supermono, with a CR enigine, very similar dimensions to a honda RS125
incredible machine went where you looked, think he paid approx £3k
he (Ben) has just bought another engine for it with nova 6 speed box
so it may be out again next year, I won't be riding it, struggled to fold my six foot two frame in to it then, and with leg hahaha

Fawlty Towers - staple humour for South African yoots growing up in the 70's and 80's - at least for me. One must remember that South Africa only got television service in 1976 LOL.
