FAQS

FREQUENTLY ASKED QUESTIONS 

Do I NEED TO REMOVE MY MAINSTAND??

EXCEPT FOR GT750 MODELS
SUZUKI GT250, T500, GT500,rd250/350 lc, gt185 AND SAMURAI

WHAT DO I NEED TO SEAL THE HEADERS??
THE HEADER PIPES NEED TO HAVE SOME SILICONE SEALANT APPLIED , ALSO A SMEAR INSIDE THE FLANGES. JUST ORDINAIRY CLEAR SILICONE SEALANT LIKE YOU WOULD USE AROUND A BATH OR WINDOW FRAME. IT WILL WITHSTAND THE TEMPERATURE NO PROBLEM ,AND WILL STOP UNSIGHTLY DRIBBLES OF OIL FROM THE FLANGES.

DO YOU NEED MY BIKE TO MAKE THEM ON??
NO, I HAVE COMPLETE BIKES HERE SO I CAN GUARANTEE A PERFECT FIT.

DO I NEED TO REJET??
OK, IT IS TIME TO UPDATE THE JETTING INFO.

THE QUESTION OF WHETHER YOU NEED TO REJET, IS LARGELY DEPENDANT ON WHETHER YOU ARE RUNNING THE COMPLETE STOCK AIRBOX.
F YOU HAVE REMOVED THE AIRBOX AND FITTED INDIVIDUAL OR POD FILTERS ,YOU WILL DEFINATELY NEED TO REJET, TYPICALLY AROUND 10 SIZES UP.
MOST OF MY PIPES ARE DESIGNED TO RUN ON STANDARD JETS, BUT ONLY IF THE ENTIRE AIRBOX AND ASSOCIATED INLET TRUMPETS ARE INTACT AND IN GOOD ORDER. I.E. NOT LEAKING AIR OR CRACKED RUBBERS.

MANY BIKES HAVE A STOCK AIRBOX, WITH SOME KIND OF REMOVABLE INLET TRUMPET OR RESTRICTOR. IF THIS HAS BEEN REMOVED ON YOUR BIKE, IT WILL NEED TO BE REJETTED WITH LARGER MAIN JETS (TYPICALLY UP 3 SIZES) ,BUT CHECK YOUR MAIN JETS AS IT MAY WELL HAVE BEEN DONE ALREADY.
THIS MAY SOUND VAGUE BUT DONT FORGET THESE BIKES ARE AROUND 40 YEARS OLD. THE GOLDEN RULE IS, IF IN DOUBT FIT LARGER MAIN JETS AND CHECK THE PLUG COLOUR, YOU CAN ALWAYS COME DOWN IF NECESSARY.

ARE YOUR PIPES ROAD LEGAL?
ALL MY PIPES ARE BUILT FOR BIKES MADE BEFORE 1981 AND ARE THEREFORE EXEMPT FROM ANY UK LEGISLATION. THEY DO STILL NEED TO CONFORM TO AN MOT TEST ,BUT THIS IS AT THE TESTERS DISCRETION.

ALL COUNTRIES OUTSIDE THE UK, I MAKE NO CLAIMS WHATSOEVER AND YOU NEED TO CHECK YOUR LOCAL LEGISLATION .
