RE: 350cc Big Bore Kit for the TTR250 - updates and gossip!

Just over a week to go until my 350 starts its first race.

Liam has a lot of confidence when riding this bike since playing with the suspension a little, and adjusting the ergonomics. We both find the bike much better to ride with my steg pegs on-even though it makes air filter access more time consuming. But we are running with the theory that he'll be riding the bike for 24 hours, but may not have to change an air filter... So stegs will have greater gain. Due to the nature of the race, we also changed the gearing from 14:44 to 13:44, but it'll still do 120kph.

The motor itself has just over 30 hours of use, and remains extremely smooth and torquey, so we have no concerns there.

We have a little more testing to do with another light, but are pretty happy with the set up. Other than that-fresh oil and tyres to be be fitted early next week... once the Hattah Desert Race is over.

With a bit of luck, Covid restrictions won't impact our ability to get there (several riders have been denied entry to the state due to border closures. If the current regulations continue as-is, Liam may be the only interstate competitor)

Good luck with the 24hr, it gets bloody cold out there overnight so get him to have layers that can be removed as he warms up. Make sure you use DOT tyres & the lights are up to the task.

Phil from Motorbiking is riding a TT250R this year so we should have at least 2 x TTR's out there proving he can get into SA from Queensland !!!!

Cheers Terry

I rode the 24 in 2006 on a TTR 250- finished with a class win... The only difference with this bike is using LED lights instead of halogen. My bike has just come through a roadworthy, so we know that it's right to go. Motoz Tractionators this year.

Unfortunately I have heard that Phil has fallen victim to the Covid lock downs and will be unable to make it.

My mate ( he also has a TTR) rang me last night to see if I wanted to come up, he's on one of the check points, I told him to keep a look out for the TTR350

Good luck & keep warm

Terry

After 12 hours of racing, Liam withdrew from the event.

1/3 the way through his second lap he was looking pretty good, despite having been thrown a few times (largely from last minute changes to the front end that we had to make due to a cracked front rim... Complete front end change) . Coming in from his second lap (at 1 am) we could tell that he was done. As he put it "racing Hattah last week wasn't a good idea" (4 hour desert Sprint on 38km track). Fighting with the different front end on a rapidly deteriorating track just exacerbated everything that he'd felt since the previous race.

On the up side, the 350 ran beautifully for pretty much 12 hours solid, and we had full confidence that it would easily make it to the end.

Well done Liam - and the 350 motor! 12 hours racing was probably the best test yet and Steve probably ought to add it to the sales blurb wink

Well done Liam for getting that far! Amazing test of man and machine and glad both came out unscathed smilesmile

Good news for the 350 owners out there.

Better to stop voluntarily than be stopped by an exhaustion induced crash! Damn good effort even making the start after Hattah. Well done and I'm glad the 350 didn't let you down

Incidentally, batch of six barrels came back from the foundry today. This may be the last batch as demand slows and the outlay weighs heavy on my bank account...

On the drive home, Liam was going through his footage, and has put a Youtube video together. (There is a little bit of swearing in the video)

In watching the footage, it's worth noting that prior to starting, the bike had been locked in Park Ferme for 22 hours- and wasn't permitted to be started until his departure time... Firing up for the second lap is at 14 minutes (give or take). I am very happy with the way the 350 started and ran throughout the event.

At the time of withdrawing, he was coming 72nd of 146, and 7th in class...

Well done to both man and machine, that was a top effort mate! Great footage too.

Great video, love the video split between day & night, lights were pretty good as well. No shame in pulling out I know plenty of guys that have taken a few years to finish the event, they learn the mistakes with what to carry & wear. But at least it was dry this year, in other years it has been very wet & would be the worst weekend during the year weather wise.

The bike seemed good with plenty of sandy loam, got to watch water holes & stick to the left, sidecars dig huge holes on the right.

Cheers Terry

 Mossproof/Steve put me down for a kit please. I was going to put it in my TTR263 but that bike goes too well. So I am building another one to replace my Wrf. Twin TTR'S!!

Going for a PWK again on this one? Should fairly easily hit 40hp.

 Yeah PWK38.  Scotty already has a new one ready for me!  I dunno about 40 hp  aim to crack 30+.   With just some head porting and with trick exhaust and suspension.  The 263cc bike is actually my sons bike I comandeered!  Time to build my own.

 Ha ha no it will remain pretty stock just bigger carb massaged head and better exhaust. Might play with different headers.  No hot cams or anything.  And no hurry from this end its all got to be build from a pile of parts that all need to be reconditioned and reassembled, motor rebuilt etc. As long as one has my name on it!!
