Evening all,
Just thought i'd post a couple of pictures of the GT 250 resto, which has been standing in a mates cellar for 16 years and has now been rescued and will be turned into the 'Mocked up' picture which is similar to the 'Pipeburn website' cafe racer bike.
Cheers
Brooky

Nice basis, but please try to avoid the F'ups on that pipeburn bike which make it basically unrideable. It has race kit dimensioned chambers and no muffling which will earn you an ASBO right there
The frame mods are good and stiffen the chassis up, but it needs mufflers, air filters and decent fenders.
Good luck and keep us posted.

Hi Tz,
yep, ur right about the silencers. Bike would be hill climbing around the southern country area though

so shouldn't be to much of a problem as i'll be thrashing up someone's tarmac'd drive from there home or a closed off road somewhere.... , ahem cough cough ...... will fit some cans on the back end to quieten things down if she goes on the road though, tis easier that way than get a few points etc etc..... though i promised the wife that the GT will not be going on the road (but she probably will do some time)
Some K&N's will be fitted to trumpet stacks on carbs.
Have you any info and knowledge of the mod's these guy's do to carb's ?

I have no personal knowledge of that company. Flow dividers have been around for a long time but they never seem to catch on and as long as the factories didn't use them, no one else was going to either. The logic was that factories are out to win and they will use any and all technology that lets them do that and since they don't use flow dividers it must be because they don't work.
That logic is less than comprehensive, but if the idea was so good, how come there are few reviews telling us all how amazing the technology is. I'm very skeptical about the idea and some of his other ideas like oversized float chambers are equally odd to me. A TZ750 can do 170 plus at Daytona with conventional crabs but a little Hodaka needs extended float chambers. How is that? I can see situations where it might be of value but I'm equally sure there are other solutions available.
Some guys swear by UFOs and others claim they do nothing. Since there is no objective data available, it's hard to know which of these techniques actually work or are a waste of time. A better is a is a pair of PWK or TMX flatslide carbs IMHO.
In teh US and Australia most race tracks have noise limits and I would expect that a hillclimb back home in the UK would have some sort of noise restrictions and unsilenced chambers won't get close as a rule.
Great little bikes the old GT250/T20 series
