Just order my Tyga Pipes..
Mild steel chambers with aluminium silencers

Power Valves

Power valves finally ready and looking really good.. Total cost including the pins 100 euro

Cylinders ready to be ported !!

Its been awhile and I am seriously starting to miss riding my rgv ... Had to sent my cylinders twice to Holland in order to have them replated since the first time , the least I can say , was unsatisfactory ... Anyway the cylinders are back and in perfect condition ... Now its time to port them and most important polish all the ports to perfection ...
Hope I will manage to ride my beauty by September ...

Power Valves Pics

This is the last problem I have to overcome .. It is very usuall problem for the VJ22 RGV .. The pin either snaps or destroys the middle part lettong it slip in to the cylinder .. The solution is either to replace all the valves with brand new aftermarket ones or place pin implants ...

I will either buy or manufacture my own implants ...

Cylinder Head Pics

I think its needless to spot the differences between the stock heads and the sweet kit spec heads by Con Dziobon .. These straight cut heads are volumed for unleaded fuel and have angled squish bamd and conical chambers .

23D70 SAPC

Browsing on e-bay found this aprillia 23D70 SAPC box ...


According to rgv250.co.uk


"Aprilia ignition box. It was derived from the 23d10, but they changed the ignition timing to be slightly retarded compared to the race-kit box, and modified the opening times of the power-valves. It has 4 degrees of pre-ignition, but with the 5 degree ignition advancer kit (FZR400 woodruff key) it would produce almost the same advance curve as the 23d10. NOTE: Having now run the box back to back with a 22D30 on the dyno
(Jan 05) no difference could be found. I wonder if the Aprilia "tweaks" are just urban myth?"
However I decided to give it a try .. It will be interesting to see if it will make any difference on a modified motor compared to the standard 22D30 SAPC..
Anyway I only paid 5 quid for it ..

My new Heads !!!

I have them for quite some time now but did not have time to update ... 
My new suzuki Rgv cylinder Heads,  the heads are volumed for unleaded fuel and they also have angled squish band and conical chambers .

Fantastic work ... excellent service...excellent product ... Cant wait to put them on ... I believe that Tygas are now up next ...


 

CARBS AND S.A.P.C

Finally I am starting to collect parts for my rebuilt . As a standard Jap spec model it came with 30mm carbs and 22D00 SAPC unit . Never gave me any problem but at the same time it only produced about 45HP .Un-restricting a SUZUKI RGV is not a difficult task all that is needed is 34mm Carbs and an un-restricted SAPC unit . More information upon SAPC units can be found at rgv250.co.uk .

Mikuni 34mm flatside Carbs

34 mm carbs for higher output and torque than the 30mm standar jap spec ones .

22D30 SAPC UNIT

" This box only opens the pilot air valve between 500-2000 rpm, and is the most common un-restricted SAPC box available"

A new or well preserved un-restricted engine should be making around 52-55HP

Both of them costed me £60 which is rather cheap if you come to think that you gain about 10HP instantly .

Next on my list : Straight spark plug Heads !!!!
