Barrels are re-bored on the latest fully automates Sussen cylinder king machine using a special two stroke mandrel. Under my personal supervision. Tolerances of 1 micron can be achieved. We can use your clearance values our own values learnt from experience to work best. 20$ per pair. 35$ per pair if you want us to bevel the port edges for you. Or INR Rs 600/-

Introduction:

We remove any casting flaws and reshape the transfers axil and radial angles are optimized. The port are not touched or modified unless its to line them up with the barrel. This is the best mod without effecting engine life. We also dial in your squish and modify your stock reed blocks.

Cost: INR 3500/- or 75$ for both barrels.

 

We do every thing in stage I plus we recommend installing RZ reed blocks with fiber reeds. The intakes are modified to take the larger reed blocks. Ports are modified and beveled to increase top end power. Again engine life is given importance. This is the best balance between engine life and power.

Cost: INR 4500/- or 100$ for both barrels. RZ reed blocks and manifolds need to be supplied by you. Or we can arrange for them at 70$ a pair. If you buy the RZ reeds and manifolds from us we will build and install a Boost bottle also.

 

All the jobs covered by stages I and II plus we design the engine to your specs and target power. Just remember the higher you go the less the engine life. You have to use the RZ reed block and 30-34mm carbs.

Cost INR 7500/- or 150$

 

These sleeves are unmatched in quality. And hardness. They have been specially surface treated. 10 times the strength of local sleeves. They have not been turned on a lathe. Both the inner and outer surfaces have been ground. The insides have not yet been honed in the pictures.
We also offer custom surface hardness from 25 HRC to 60 HRC based on your requirements.
We also offer to coat the liners with for you. 

Available in std configurations for the Yamaha RD350.
a. LT (Indian RD350 Low Torque)
b. HT (Indian RD350 High Torque)
c. US Spec RD350
d. Hybrid (TZ shaped transfers, Bridged intakes, designed for 10,000 RPM redline)
e. You design the ports we cut to spec.

Price installed and fitted in RD350 barrels. Approx 150$
Rs 7500/-. So for 150$ you have a new set of STD bores that exceed the factory specs.
(Warning once treated further porting of the barrels is not recommended or may we say possible).

 These sleeves allow you to extract far more power than possible with the stock liner, which tends to wear very fast at high RPMs.

Cost for Pre Cut liners : 80$ pair

If you send us your old barrels. 150$

If we supply the barrels with liners inserted and ready for use. add 25$. 150+25=175$

Items you need to send us.
