Raven1294 Posted June 5, 2017 Share #1 Posted June 5, 2017 Should you rejet a 2005 Royal Star Tour deluxe that has K&N Filters? Just purchased an 05 Royal Star and found out someone had installed K&N filters, and I am about to go on a 5,000 mile trip from Texas to Jasper/Banff Canada and will be riding at high altitudes here and there, 11,000 ft elevations along the way, don't know if the bike was ever rejetted yet it appears to be running very well with stock exhaust, just curious whether rejet is in order....any thoughts?....Thanks Link to comment Share on other sites More sharing options...
RSTDdog Posted June 5, 2017 Share #2 Posted June 5, 2017 Should not need a rejet. K&N filter in the stock air filter housings will not flow (appreciably) any more air than the stock paper elements. With stock exhaust you should be good to go. Check the K&N's are clean and properly oiled. These bikes really don't like the stock airbox messed with. Refrain from opening up or making things larger, adding holes etc. Affects the driveability. The valve clearance inspection at 26,000 is the most important thing you can do. depending on how many miles you have on a used bike you should find out if this was done.

The bike has those billet aluminum chrome air box covers with the Yamaha logo not sure how different they are from the stock air box setup, as far as the valves go the bike currently has about 12,500 miles on it and not sure if it was ever done, from what I have read about the valves was thinking I could wait until about 50,000 to 60,000 miles and have them checked at that time.

Flyinfool Posted June 5, 2017 Share #4 Posted June 5, 2017 Quickest way to see if you need to do something is to pull the spark plugs and see if it is running rich lean or just right. Anything else is just a guess. Link to comment Share on other sites More sharing options...
mm482 Posted June 6, 2017 Share #5 Posted June 6, 2017 I have the Chrome covers with K&Ns too, no need to rejet Earl Link to comment Share on other sites More sharing options...
Raven1294 Posted June 6, 2017 Author Share #6 Posted June 6, 2017 Thanks everyone! I will not worry about the filters, also realized the higher in altitude I go the richer it will run, less air more gas, for some reason I was thinking the other way around.
