Yamaha RD350/R5 Head Gasket (All years) - High quality copper reproduction head gasket, replaces OEM 278-11181-01 -

Replacement RD250/350/400 Carburetors - Mikuni VM Round Slide Series 28mm Carburetors (pair). Original carburetors for the RD250/350/400 are no longer available from Yamaha. However, Mikuni does offer new VM28 round slide carburetors that are very similar in function and appearance to the original RD carbs. They do require re-jetting, a new throttle cable and optional oil injection. We include a 2 line cable for bikes that use premix or a 3 line cable if you choose the oil injection option. The oil injection option includes new oil nozzles. These carbs are only available with left hand idle screw and have individual choke levers (no choke crossover between carbs). We can jet the carbs for a stock RD250, RD350 or RD400 or for your specific application if you have pipes and other modifications that require jetting changes. Please submit a note with your order upon checkout for jetting changes required, if additional information is required we will contact you. Carb sets are built to order, please allow 5-10 days for shipping. You should let us know the year/model of your RD and any modifications, pipes, air filter, porting, etc. Note: The oil injection option is not required for the R5/DS7. -
Yamaha RZ350 (US Versions) Fork Caps with Preload Adjusters CNC Billet Fork Caps with Pre-load Adjusters. Note: These are for the 84/85 US RZ350 (35mm fork tubes) The common misconception with pre load adjusters is that they increase spring tension. What they really do is allow you to adjust sag correctly. With all the suspension mods happening with these bikes it's easy to end up with the wrong sag. Even with the correct spring rate for your weight, you cannot always get the optimal sag without opening up the forks and adding spacers or cutting springs. These give you about 20mm of adjustment, which when combined with the proper spring rate, will allow you to set sag perfectly and adjust it for your weight and riding style. These also have graduation lines on the stems for easy reference when adjusting. Note: Fork tube size is 35mm,  cap thread size is 31mm x 1.5 pitch. Sold in pairs. Kit includes 2 fork caps with pre-load adjusters, o-rings, fork spring discs and installation instructions. Yes you will lose the air forks with these adjusters, but air in forks doesn't work very well as it compresses exponentially. Switching to some of the better after market fork springs and these adjustable pre-load fork caps will really dial in your suspension.
