I have also considered that possibility, but I was aiming way too high.  If a well tuned RD400 can make say 72hp, then surely a triple could make 106 or maybe more in a drag race motor.

First issue might be moving the cylinder studs and the second would be crankcase moth mot being close to matching RD transfer ports and of course the perennial issue of can I squeeze an RD cylinder between the two outer pots.

What would probably be easier to achieve is to fit reed boxes and bore it to 63mm.  I am assured by those that know that 63 or 64mm is the absolute maximum bore size but with a little more boring and some welding and plating, something slightly larger (say 66.5mm) might be possible.

Ian Reed in teh UK has done some interesting things with his 380 triple and of course there was a 500cc water cooled Barton version of the 380, so anything is possible.

A client of mine bought his Vape directly from Europe for a GT500 PEI system, but the kit was incorrect and they could not work out how to fix the spacing issue.  I contacted Dan at RE-MX and half expected him to tell me to piss off as he didn't sell the unit, but he was extremely helpful and solved the issue and sent me the necessary parts at no cost.

I would strongly recommend buying Vape products from RE-MX.  He knows what he is talking about and goes above and beyond the call to make it right. I will not buy directly from VAPE again or other suppliers. Re-MX is the place to go.

General Chatter / Re: Where's the water pump?

Looks like an electric pump in front of and slightly above the front of the cylinder head.  An A/C RD350 clutch cover is an interesting choice.  Tank looks like a TZ F/G model and radiator is aftermarket with a remote filler neck and probably thermostat housing which could be RZ or from an FZR.  R6 front end perhaps, with Scitsu tachometer and what appear to be Jim Lomas pipes without labels.

Cool bike.

Before you modify more circuits, go back to basics.  Check the connector to the key switch and see if you have power to the switch and then see if you have power coming out of the switch to the various circuits.  And check the connectors at that huge assed battery stuffed in there. 

One trick I learned to check battery condition is to fit a battery tender pigtail for charging and just plug in a battery tender voltage tester. You can quickly wee battery voltage  as you turn on different circuits and when it's running you can see voltage as it charges.

We had a more or less stock Mk2 RG250 years ago and even with a slight clean up of the crankcase reed ports, it was way faster than our RD400s mainly because it handled so well.  It seemed to carve through corners where the RD250 and 400 felt like a a lead frame.  They didn't wobble, as such but the RG just felt lighter and more confidence inspiring.

I'd love an RG250 rolling chassis to drop my RZ350 motor into to build a Yamagamma for even more fun.

Looks like another Richard "Filth" Lindoe machine.

Anyone know if it's a rebuild of the Incredible Kettle or another along the same lines?

wOW.  A TA125 in street trim.. :whistle:  :rolleyes: We had a CS5 at one time.  Great little bike to thrash around on and for some reason that escapes me , I said NO to an actual TA125 many years ago.

Are they same pipes as the original Toomey's and as the ones that FPP made and sold?

Yep.  They shipped a hybrid by the looks of things.  Mounting plate is clearly for points type, stator coils are common to both I believe, as is the HT coil, but they confirmed that it had the correct rotor and instructions. Looks like someone pulled the wrong stator assembly.  They are being totally responsive so far and if they will ship the correct mounting plate, we'll be good to go.

I just had a Vape system delivered for a GT500 to replace the PEI.  It looks slightly different to the pictures on the web site but beautifully made.  The invoice and shipping docs confirm that it's the PEI replacement and not points replacement, so I fitted the stator and wired it all up with only a few small changes to the wiring that was supplied.

When I fitted the rotor, it didn't look right.  The rotor is too far out or the stator is too far recessed, so I took a deeper dive and looks like the wrong unit was shipped. I had hoped to finish the install this weekend, so now I have options.  Get the unit returned to VApe in Europe, or get an adapter plate machined to space the stator out by about 8mm.

Anyone run into similar problems with a T500 or GT500 Vape system?

OEM crank bearing I believe are NLA but you can use CrusinImage or fit different bearings into an adapter sleeve. heads can be welded and machined to a nice new squish shape which would be more efficient as well as fixing the cracks.  Or fit inserts (domes) into the stock head shell.

A few years ago (well, a lot more than a few) I had a short term need for a bike to ride on the street to commute on and a friend offered me his Ossa SDR.  Street legal, off road enduro. It was awesome. Nothing against the usual suspects but you might want to add a something Spanish to your list of possibilities.

I know I have a new 2.50x18 36 hole and pretty sure I have a couple of good or new 2.15s as well if you are interested let me know (PM or email me) and I'll dig them out
