December 18, 200619 yr I have a 04 Beta 270 but it seems to have no power and doesn't clean out! anyone any ideas what it could be?
December 18, 200619 yr Have you tried all the usual stuff? Specifically: Whip the carb off and give it a good clean making sure all the jets are clear. Also, make sure the air filter is in reasonable nick and not clogged (if possible, put a new one in). New plug. Might also be worth repacking the silencer.
December 18, 200619 yr Author yh tried all them, new spark plug, new exhaust packin, cleaned d carb (it has original jetting), made sure the timin is correct! it jus seems like it oils up straight away! anymore ideas?
December 18, 200619 yr Author Compressions fine, it sounds alright when i first start it up but then it oils up straight away and just has no power at all!
December 18, 200619 yr What notch is the needle set at? Really clogged up mid box can cause bad fowling, worth giving it a good clean along with the front pipe. As bilco said check the compression as well
December 18, 200619 yr Author Never changed the needle since new, what should it be at? and what jets should be in?
December 18, 200619 yr Standard jets are 30 and 150, needle setting is middle, most of us lean the needle one notch from new. I have 27.5 pilot and 145 main as mine was bogging and running too rich from new, it has cured the running but be carefull as it may make other bikes too lean. Use premium pump fuel and I use 65ml of TTS in 5 litres,
December 18, 200619 yr Author ok thanks, i normally have 70ml of oil in 5 litres of fuel. My plug is always black, which points to it being too rich! It has never ran right even from new! Had problems with stators but the latest ones an 06 one and seems fine!
December 18, 200619 yr Is it not closer to 80/1 now or higher? Sarah are you over oiling your filter?
December 18, 200619 yr Author is what not closer to 80/1? no am defnitly not over oiling my filter and i change it every week!
December 18, 200619 yr is what not closer to 80/1? no am defnitly not over oiling my filter and i change it every week! Think hes on about the oil/fuel mix I run my 250 at 75/1 with TTS but heres a calculator thanks too the guys down South HERE
December 18, 200619 yr is what not closer to 80/1? no am defnitly not over oiling my filter and i change it every week! 4 Ltrs of fuel and 50ml of oil will make it 80/1 i think you are running on the rich side, some even say run it at 90-100/1. Not the soal problem but wouldn't help.
December 18, 200619 yr Author ok thanks for everyones help i wil try some things out and mayve get back to you's! Thanks
