Honda SH150i Valve Check/Adjust

[@timdoyle8199]

Yep I've gone through that, you have to hold the center while you tighten the nut !

[@paapali]

ookay, for anyone that still might watch this: when you tighten the nut, use a screwdriver to hold the thing you adjust still- that way you only have to do it once instead of 50 times each.

[@janvanderkruyk]

I agree, and after adjusting it first tight the nut a little and check again if it's still okay before tighting it completely.

I have knocking at idle, feels like something metal is lose and bouncing on vibration every few seconds at random times I mean it doesn't have rhythm so to speak. My bike is new on 5000 miles, I only changed the oil so far.

+Drererere DerererereIf it helps anyone turns out this was a worn out chain tensioner (5k miles) and apparently it's a very common problem.

DaBinChe, You are the best, watched all your videos and my SH150i is in tip top condition. One of the best scooters around, still.. Better that the PCX [I'm 56] PCX is to Bubblegummy for me.. Just the ticket for the traffic crap in Sydney... Not to mention the parking..

[@DaBinChe]

+Duke SPEED Yeah I think the SH150i is the best 150cc scoot...also why it is Italy's #1 selling scoot

[@priseene]

Not hard to see why, Question? installed what would you recommend for a replaceemt belt ?

[@DaBinChe]

+Duke SPEED the OEM belt, stock belts are the best!

Hi, now I am owner sh 125i, year 2016 bought as new. I can't find mark for top position of valve. Thank you all best

[@DaBinChe]

use the mark on the cam sprocket and a pen in the spark plug hole

[@04poppop]

@@DaBinChe Firstly I just move intake and exhaust to position both closed, that is when they reach max height. After staring it was terrible, very rough sound. Later I found that wheel you have to move is behind radiator (on your model radiator is on the front) my got it on right side, took off radiator and on that wheel there are marks T and I think F. So moved to position T. On frame is mark so fited with F. But result same very rough sound. On intake 005 on exhaust 010. I try to play with it but don't see much positive prospect. Guy in servisu can do it but 40 pound just for collection and 80 pound got job. If you know it's max 15 min job

[@DaBinChe]

@@04poppop The T and F mark goes around twice for each time the piston is actual TDC on the compression stroke. The other time it is TDC at the exhaust stroke. So you have to make sure you are at the TDC compression stroke. That is why you need to double check the cam gear marks. The adjustment is about 20min. but taking all the crap off is easily twice as long so figure it to be an hour labor at least.

VALVE IN 0.16 EX 0.24

[@marcoeusebi8487]

[@farmoboy83]

Any idea of a tutorial for honda sh300i?

[@DaBinChe]

farmoboy83 We don't get that model here in the USA..but it should be very similar

[@farmoboy83]

Do you always reuse the rubber gasket? Any need of special gasket seelant?

[@DaBinChe]

+farmoboy83 I always reuse, I think honda says to use a new one

[@farmoboy83]

how do you know which valve is the intake or exhaust side?

[@DaBinChe]

+farmoboy83 the one on top is intake, bottom is exhaust

[@thiennhannguyen6241]

Please help me adjust valve sh125i 2011. I need sh125i's Standard parameters

[@DaBinChe]

i have no idea what the specs are for it, it is not sold here

[@thiennhannguyen6241]

i'm just wanna know how to adjust valve for my sh125i, my sh125i has valve problem

[@DaBinChe]

If the sh125 is anything like the sh150 then just follow the video, otherwise I have never seen an sh125...they aren't available/sold here

[@tbillyjoeroth]

Need to throw in a little swearing to make it more realistic. Thanks for the video.

[@TILL_OFARIM]

03:27 what?!

[@DaBinChe]

If you follow Honda's service manual it say to line up the timing marks to be at TDC. You don't really need to go by the marks, just need the cam lobes to be on the opposite side of the rocker arms. When the marks are lined up both intake and exhaust will be closed. When not using the timing marks as long as the cam lobes are not activating the rocker arm it is fine. In this case the rocker arms are at the top of cams so if you set the cam lobes pointing at the piston they will be away from the rocker arms
