Pulled the clutch down and found the shaft was stiff to turn ,got the seal out and the shaft had a rough spot on it ..Cleaned it its now much better.
The spring were wound all the way in so I checked them next too the TS clutch springs they are much shorter and red so they must be betterIts too late to test now fingers crossed ...The carb rubber has now been epoxy onto the spigot for now ,I have to test at the track this weekend its the last time before Taupo.
Yeah rubber always sticks well to epoxy. . . Fix it or your GP will be a pushfest.
Don't you look at my accountant.
He's the only one I've got.
Is this a 100cc or a 125cc motor?
I see photos :- http://www.flickr.com/photos/hz13/se...729897/?page=2
Michelle got some good photos. So how did it go? Whats it like to ride................
Its a TF 125 ,It goes well plenty of bottom end and pulls all the way .The handling feels so light after the FXR it tips in so easy ,I only got a few laps in the dry and was taking it slowly but first impressions are good ..Got it on the scales and with half a tank it is ..........73kg brilliant its 30kg lighter than the FXR .
I need to shorten the clutch cable and sort little bits but I'm pleased so far ...lets see what falls off or breaks today !!!![]()
Your 28mm carb is not within the rules. You are allowed 24mm max on a 125 aircooled 2 stroke. Your 24mm runner does not make a bigger than 24mm carb legal. Better to find out now and fix it than to get protested at the track. I am surprised no one else has pointed this out. I even saw a pic of Green looking at it in the pix from Mt Welli yesterday.
Nice looking bike though.

Go Talk to TZ about modifying the carb to make it legal and still flow well[/QUOTE]
Do tell TZ, how is this done?
Me and TZ were chatting about this the other day. The kart guys have carb rules as well but they specify where in the carb the measurement is made. Bucket rules don't, so the crafty among us have installed a part that has a 24mm diameter in the carb past the metering venturi. This part, due to it's design, flows more than a 24mm carb. This part is installed in carbs larger than 24mm. If it's installed as part of the carb then technically the bucket rule as written has been complied with.
[QUOTE=jasonu;1129936060]Your 28mm carb is not within the rules. You are allowed 24mm max on a 125 aircooled 2 stroke.
Yeah I think if Rick proves unstoppable we might have to protest, problem is 24-2-4 is worded "equivalent to a single 24mm" as such any old restriction to 24mm in the carb outlet complies with the rule.
Who (someone whos decision carries some weight) said if the part installed as part of the carb it complies with the rules? Has anybody tested this modification with an actual protest? Has this been brought to the attention of MNZ scrutineering or technicial staff that might, in the future, be involved with any protest? What is John Connors opinion? If the point of measurement is not specified, where exactly would an official get his measurement from? What is stopping the official from takeing the measurement from another part of the carb that is still bigger than the allowed 24mm and disqualifing the bike?
To me, this sounds like some sort of tricky loop hole that could result in a bike being deemed illegal as the official can (it seams) take a measurement from anywhere, and also some might say it is not within the 'spirit' of the rule as when you (Mike) put this rule to MNZ I know the intent was for a 24mm or equalivient carb and this was not forseen.
I don't like it and think someone should look at modding the rule as to exactly where the measurement is taken as in the karting rule you mentioned.
I for one would protest it in a championship or title situation (that is if I ever get myself into that situation which is highly unlikely).
Is anyone else using this part? How about posting a picture or two, I would really like to see what you have done.
The rules do state that it is restricted to the equivalent of a 24mm carb. So placing an insert of 24mm into a larger carb would not then be equivilent to a 24mm carb, because as you say speedpro it still flows more than an actual 24mm carb would.
I see what you are saying that by placing the insert in there, at least some of it has a diameter of 24mm but I don't see it to then be the equivalent of a 24mm carb. To be the equivalent of, it would need to have a 24mm sleeve put in right through the carb? Or at least on the intake side before the slide?
That at least is my own humble, unexperienced opinion. Be interesting to hear an official take on it. (or as official as buckets can get)
The convention is that Carbs are sized at the major venture, carbs can have more than one venture, in fact its common for carbs to have ventures within or upstream of other bigger venturies, take a look at a Holly or Rochestor or even the carb on an older Jap car.
Not all carbs of the same size flow the same amount of air, we have checked quite a few with our simple flow bench and found ways to improve them.
Are Buckets to be limited to unmodified store brought 24mm motorcycle carbs and ideas?
Inventiveness is within the spirit of Bucket racing, and this carb mod this has been run past JC and he was OK with it.
Maybe he was more relaxed about it as all the details and theory have been posted on the ESE thread so anyone can copy it if they make the effort.
I will dig up some of the posts...........
