IF you race a “stock” class and want to win YOU NEED a good Valve Job to WIN!

If you are building or rebuilding your own small engines, either for performance or just a quality rebuild, this gives you control of cutting or re-cutting your own valve seats. You can do a standard 45 degree seat or a 3 angle performance seat with this set… You can move the sealing surface on the seat for best performance.. This is ONLY if you have 5mm or 5.5mm valve stems, and includes the following. 22mm×45° 24mm×45° 27mm×45° 31mm×45° 22mm×58° 24mm×58° 27mm×58° 31mm×58° 20mm×30° 23mm×30° 26mm×30° 30mm×30°Grinding Stones: 21mm×45° 24mm×45° 26mm×45° 30mm×45°Guide Pilot: Diameter 5mm, Diameter 5.5mm. Please know this is for hobby builders Racers who build their own engines, or small volume high performance engine builders, If you are building your own racing Kart, Trike, or mini bike, or any engine with 5mm or 5.5mm valve guilds, then this will put you well ahead of those who do not have the ability to have a 3 angle or multi angle valve job. Or if you don’t want to wait weeks to have it done from some outside “machine shop”… Even do a few valve jobs for friends and this will pay for itself MANY times over, The seat cutters in this kit have performed very well for me… This is NOT rocket science, I personally usually do not use the the included grinding wheels and I get a very good sealing surface with just the cutters. I use the cutters and then lap in the valves. It takes me 10 to 20 min to get the cuts and the seal I want on a small performance engine. This is a great tool to learn and experiment with what works with your situation without depending on others and their opinions. I can honestly say I have never gotten a better valve seat from an outside machine shop than the ones I CUT on my own with this set. If you race a class that does not allow porting then a good valve seat/ valve Job is the best thing you can do for increased performance. NOTE: If you race a “BOX STOCK” class you can bet the winning engines have a good valve job, If you Race a “claimer class” this is a zero cost performance boost, that costs nothing but a few minutes on the bench, This is a MUST have Tool.
