Query Slowness

Hi there I have the following query I am running to get more information from multiple tables on my database of products:

SELECT
category AS Manufacturer,
brand.displayvalue AS brand,
productcode AS SKU,
descr AS Short_Description,
fulldescr AS Long_Description,
product_type.displayvalue AS Prioduct_Type,
colour.displayvalue AS Colour,
printer_model.displayvalue AS Printer_Model

FROM xcart_tmp_products

LEFT JOIN product ON xcart_tmp_products.productcode LIKE product.mfgpartno
LEFT JOIN productattribute brand ON product.productid = brand.productid AND brand.attributeid = '33113319'
LEFT JOIN productattribute product_type ON product.productid = product_type.productid AND product_type.attributeid = '331100'
LEFT JOIN productattribute colour ON product.productid = colour.productid AND colour.attributeid = '331100'
LEFT JOIN productattribute printer_model ON product.productid = printer_model.productid AND printer_model.attributeid = '331100'

WHERE forsale LIKE 'Y'

The problem I am having is the above is taking far too long is there anyway of speeding this up and thus improving my own ability within SQL?

I put the LEFT JOINS in with specifying the attributeid since I wanted the results to be in the same line as each row so each row showed more data than what was on xcart_tmp_products table you see.

I was just wondering and thanks for any help in advance,
Jeremy.
