TRRS is a cool meeting chaos, Get your entry in ! Ive entered in pre 82 (RD) and pre 89 (TZR or RGV) which ever one is back together in time
Back to my shed now, There is a hill climb on tomorro that th Rd will be "run in " at , and the engine is sitting on my bench still

[woodyracer]

god luck with the RD have you found a reason for the random engine problems?

i think at one stage we were talking about how choas is setting his bike up, {thats was about 70 pages ago...lol}

well after many many many laps and changes to the suspension im confident i can hit jenian corner in 5th pinned if not half pinned. should give me an extra second off my time there. plus ill gain some more ground in castrol.

so im aiming for a 1.22-1.25 this weekend at the race.

trrs looks like a no go. need to save up for new transport (STILL)

Sounds fun dude! How much adjustments has your bike got in terms of suspension? That's one thing I never really looked at on Hyosungs. I just assumed it was rear pre-load only.

[meowmix]

As far as the rear goes, it is just preload. Then on the front you can add shims etc and change the oil. Thats about as far as it goes. Can slap a gixxer shock in without too much hassle though, that'd be nice.

[puddytat]

Only thing your allowed to change in the forks are wieght of oil & quantity..."all other fork internals must remain as originally supplied by the machines manufacturer"

[gatch]

Adding shims for preload is counted as modified internals ?

[puddytat]

Id've thought.....
I talked with a young fella at the races over the weekend, he was going to get in touuch with MNZ to "clarify"....
Guess who got first in King of Ruapuna Streetstock Senior
helped a tad by being the only one in the class
Still it looks nice on the shelf

for this class you can only use stock shocks but the rear spring can be changed and you can put shims in the front shocks


edit: i did ask the class oficials at amcc

Yep. found the problem, The crank centre pin twisted and the 2 cranks halves got out of phase . One piston at BDC and the other one 8mm still down the bore. Checked the timing and left 1.5mm BTDC and right 9.5mm No wonder the piston from the 2nd blow up looks like it had been gas cut lol. The 1st seize on the saturday I think the crank may have moved slighty and let go all together on sunday(after getting my PB too)
I spose it does put a bit of strain on a crank with a top gear sieze at 9500rpm, new tyre too only done 15 laps and a big flat spot

Mint, I used to cane around the port on my spada, not race conditions of course but still.. That would be bad as fuck..

Oh dear.. A fella I know who races a hotrod h2, holed the middle piston at the last round of the classics register, turns out he had swapped tank breathers over when he had the tank painted, the breather was completely gummed up, with the bike running on methanol it was drinking gas and obviously couldn't suck enough in.. Lucky it didn't nuke the whole motor, at one point it did a massive back fire and blew an air filter to pieces..

Its one of those things on my "to do" list.....sat on the sideline for years thinking "thats got to be a major buzz"
Feeling a lot more relaxed about this than when Greymouth was looming...
.Not nearly as many power poles, seats,concrete rubbish bins as Greymouth either, though as soon as we got going I promptly forgot that anyway...
