Sorry forgot, "we can engineering" in Hastings made the gears for me about four years ago, cost me a "piano" Al
I have an old piano in the woolshed if anyone wants it? Welcome Alvin, See- you have already recouped your membership fees with the hallowed advice network. If only our other new members would post an introduction...

ah...the two major requirements for being part of this group......leak oil and remember a time before cell phones....
There was TIME Before cellphones??????????????? Come on now cmoore you're joking aye?Welcome Ascott, I see you've found the rabble then.
yes there was...and don't even start me on twatter or facebook.........
didn't know you old enough to remember the "tomtom drums" cmoore
The NOS T500 barrels turned up yesterday, very nice box the guy had made for them too, I eagerly removed them from thier entrapment, the first a r/h T500 with grease coating to the bore, sweet as! the next to see the light of day was a l/h FUCKING GT500!!!! FUCK ME!!!! Exactly what I have now!!!! Hey Zoos! $820 paper weights! I will fit the new steering head bearings to my gixxer, and contemplate my next hopefully less disasterous move! Al
I know how you feel, I got a set of 500cc heads for a BMW project as few years ago...hard to find.....they arrived and they looked great.....apart from the fact they were 600 heads....which I already had two sets of..... its a fine line between sellers who know what they have and appearing to ask too many obvious questions......Can they be welded up and re ported??? ( non 2 stroke owner [ apart from the kdx200] question?)
Ascot, although it's not want you want , it appears the seller is technically correct is describing them as T500 barrels. Checking the Suzuki parts fiche, we find the history of the barrel changes (this is going to be hard without a table function 1969 RH part 11210-15100 Suzuki supercession to 11210-15101 ..........LH..........11220-15100..................................11220-15101 1970 As 1969 1971R as 1969 1972J RH part 11210-15101 ie the part to which the earlier models are superseded ..........LH........11220-15101 ditto THEN comes the difference. Smaller inlet ports (to improve the fiendish fuel consumption) and smaller main jets to match - 97.5 instead of 150 1973K RH 11210-15301 LH 11220-15300 Then another change TO THE LH ONLY (don't know what the change was), which was the last change until the end of the model, including GT 1974L ; 1975M ; 1976GT and 1977GT are ALL RH 11210-15301 LH 11220-15301 The GT Barrels are the same as the later T500, except that the inlet manifold studs must be changed (part 01421-08258 instead of 01421-08268 and the manifolds and carb jets change yet again) So your J model SHOULD be early barrels. But, of course, who knows what may have happened in 40 years The Cobra and late Titan/GT barrels can be distinguished by different bridging in the inlet port . And, maybe, by the number of fins, 10 versus 11, but that seems a very confusing point. There's a good deal of talk on the web about the GT barrels being different but it's not supported by the Suzuki part numbers. I suspect people have tried to drop a GT barrel onto an earlier engine and found that the manifolds don't fit, then found that the ports are different to the pre-9173 models ,and assumed it was a GT modification. But it was actually a T500 change, mid life. The earlier barrels can be used on later engines , and vice versa, so long as appropriate changes are made to manifolds (and studs etc) and carbs (somewhere along the way they changed from 34mm to 32 mm ) and jetting. Though running one early and one late might make for slight roughness? EDIT: I think the 10 fin barrels were pre 69 , on the short lived short wheel base model. The pistons were different also, with inlet windows in them. 10 fin barrels and pistons are not interchangeable apparently with later ones. All 69 on models have interchangeable pistons though somewhere along the way the pistons were changed for the stronger but timing-identical and sizing identical GT750 ones (GT750 has two right hand and one left hand T500 pistons - or one right hand and two left hand, I forget which).
hell of a stutter there ixion...
Forvsome reason if I edit a post it keeps both the old and the new version. I'm a big believer in backups but this is silly
